Members of FCA include Zhejiang Huayou Cobalt, Sono Motors, the Responsible Cobalt Initiative, Fairphone, Glencore and Tesla, Inc.[108][109], Research is being conducted by the European Union on the possibility to eliminate cobalt requirements in lithium-ion battery production. The development of wear-resistant cobalt alloys started in the first decade of the 20th century with the stellite alloys, containing chromium with varying quantities of tungsten and carbon. [117] Smalt was widely used to color glass and as pigment for paintings. CH3OH: 12 / 32 = 0.37 Calculate the percent by weight of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl) Calculate the molecular mass (MM): MM = 22.99 + 35.45 = 58.44 ; Calculate the total mass of Na present: save. Kshitij G answered on June 06, 2015. The adenosyl version of B12 catalyzes rearrangements in which a hydrogen atom is directly transferred between two adjacent atoms with concomitant exchange of the second substituent, X, which may be a carbon atom with substituents, an oxygen atom of an alcohol, or an amine. [139][140], The "coast disease" of sheep in the Ninety Mile Desert of the Southeast of South Australia in the 1930s was found to originate in nutritional deficiencies of trace elements cobalt and copper. Divide each element's mass by the mass of the compound to find the percent by mass. During discharge,[clarification needed] the lithium is released as lithium ions. [118] In 1780, Sven Rinman discovered cobalt green, and in 1802 Louis Jacques Thénard discovered cobalt blue.

Mass percent composition of a molecule shows the amount each element in a molecule contributes to the total molecular mass. Mass percentage is one way of representing the concentration of an element in a compound or a component in a mixture. Before the 19th century, cobalt was predominantly used as a pigment. = Percent Composition: Total mass of compound (Whole) Example 1. Cobalt can be effectively absorbed by charred pigs' bones; however, this process is inhibited by copper and zinc, which have greater affinities to bone char. (a) \mathrm{BCl}_{3} (b) \mathrm{As} \mathrm{Cl}_{3} (c) \mathrm{GaCl}_{3} (d) \math… Recent growth in production could at least partly be due to how low mining production fell during DRC Congo's very violent civil wars in the early 2000s, or to the changes the country made to its Mining Code in 2002 to encourage foreign and multinational investment and which did bring in a number of investors, including Glencore. Therefore, the percent by mass of nitrogen in ammonium nitrate is: 100[(2)(14.0067)/80.04] or 35.00 %, to the justified number of significant digits. [115] Hydroformylation of alkenes often uses cobalt octacarbonyl as a catalyst,[116] although it is often replaced by more efficient iridium- and rhodium-based catalysts, e.g. It produces gamma rays with energies of 1.17 and 1.33 MeV. Transparency Market Research estimated the global lithium-ion battery market at $30 billion in 2015 and predicted an increase to over US$75 billion by 2024. Sample Problem 3.6 Calculating the Mass Percent of Each Element in a Compound from the Formula PROBLEM: Glucose (C. 6. Cobalt is considered toxic for marine environments at high concentrations. [103], Since child and slave labor have been repeatedly reported in cobalt mining, primarily in the artisanal mines of DR Congo, technology companies seeking an ethical supply chain have faced shortages of this raw material and[104] the price of cobalt metal reached a nine-year high in October 2017, more than US$30 a pound, versus US$10 in late 2015. [87] The mayor of Cobalt stated that the people of Cobalt welcomed new mining endeavours and pointed out that the local work force is peaceful and English-speaking, and good infrastructure would allow much easier sourcing of spare parts for the equipment or other supplies than were to be found in conflict zones. A subsidiary of Zhejiang Huayou Cobalt, one of the world's largest cobalt producers, Congo DongFang supplied cobalt to some of the world's largest battery manufacturers, who produced batteries for ubiquitous products like the Apple iPhones. [136] In humans, B12 has two types of alkyl ligand: methyl and adenosyl. [85] The companies in question denied their involvement in child labour.[86]. [72], Human rights activists have alleged, and investigative journalism reported confirmation,[73][74] that child labor is used in mining cobalt from African artisanal mines. Divide the component's molar mass by the entire molecular mass. [PDF]. Corporate pieties about an ethical supply chain were thus met with some incredulity. [120][121] Aureolin (cobalt yellow) is now largely replaced by more lightfast[clarification needed] yellow pigments. [70][75] This revelation prompted cell phone maker Apple Inc., on March 3, 2017, to stop buying ore from suppliers such as Zhejiang Huayou Cobalt who source from artisanal mines in the DRC, and begin using only suppliers that are verified to meet its workplace standards. Glencore's Mutanda Mine shipped 24,500 tons of cobalt in 2016, 40% of Congo DRC's output and nearly a quarter of global production. The percent composition of a compound is calculated with the molecular formula: divide the mass of each element found in one mole of the compound by the total molar mass of the compound. [67][68] Glencore's Katanga Mining project is resuming as well and should produce 300,000 tons of copper and 20,000 tons of cobalt by 2019, according to Glencore.[63]. [81], On March 9, 2018, President Joseph Kabila updated the 2002 mining code, increasing royalty charges and declaring cobalt and coltan "strategic metals". a) CO. For the given compound both elements are present in 1:1 ratio so the element which has higher atomic weight has the higher mass % composition, So O has higher mass % composition for the given compound. It is simply calculated using a basic formula dividing the mass of the element (or solute) by the mass of the compound (or solution). Finding the mass percent requires the molar mass of the elements in the compound in grams/mole or the number of grams used to make a solution. [94] Nickel-cadmium[95] (NiCd) and nickel metal hydride[96] (NiMH) batteries also include cobalt to improve the oxidation of nickel in the battery. The percent composition can be found by dividing the mass of each component by total mass. Here, number of carbon atom is same in each compound. Since there is only one Sr in every compound, the mass will be the same: 87.62g/mol Sr Now divide the molar mass of Sr by each of compounds' masses: 8H2O) and spherocobaltite (CoCO3). Each element's contribution is expressed as a percentage of the whole. Georg Brandt first showed cobalt to be a new metal in: G. Brandt (1735) "Dissertatio de semimetallis" (Dissertation on semi-metals), Donaldson, John D. and Beyersmann, Detmar (2005) "Cobalt and Cobalt Compounds" in, Central African Mining and Exploration Company, Occupational Safety and Health Administration, National Institute for Occupational Safety and Health, International Agency for Research on Cancer, Economy of the Democratic Republic of the Congo, Mining industry of the Democratic Republic of the Congo, "Atomic weights of the elements 2013 (IUPAC Technical Report)", "Electric car future spurs Cobalt rush: Swelling demand for product breathes new life into small Ontario town", "Cobalt oxide surface chemistry: The interaction of CoO(100), Co3O4(110) and Co3O4(111) with oxygen and water", "Zur Kenntnis des asymmetrischen Kobaltatoms. Subtract to find the mass of oxygen in the compound.

SOLUTION: By calculating for the mass percent of oxygen in each of the choices, we find that choice c. {eq}Mg(NO_3)_2 {/eq} has the highest mass percent of oxygen. High levels of Co and Se have been recorded in seafood sourced from coastal areas with higher levels of the trace metals. For MgS, it would be [32.0/(24.3+32.0)]*100=~56.8% mass sulfur. Disclaimer: I'm going to estimate all my masses. Leaching with water extracts the sulfate together with the arsenates. Steps to calculating the percent composition of the elements in an compound. [64], The products of the above-mentioned processes are transformed into the cobalt oxide (Co3O4). [135], Proteins based on cobalamin use corrin to hold the cobalt. Cobalt from radiotherapy machines has been a serious hazard when not discarded properly, and one of the worst radiation contamination accidents in North America occurred in 1984, when a discarded radiotherapy unit containing cobalt-60 was mistakenly disassembled in a junkyard in Juarez, Mexico. 69.58%. • The percentage of a given component in a compound is the mass percent of that component. A number of observers have called for tech corporations and other manufacturers to avoid sourcing conflict metals in Central Africa at all rather than risk enabling the financial exploitation, human rights abuses like kidnappings for unfree labor, environmental devastation and the human toll of violence, poverty and toxic conditions. (You should not have to perform any detailed calculations to answer this question). The percent composition is used to describe the percentage of each element in a compound. Cobalt-57 is used as a source in Mössbauer spectroscopy and is one of several possible sources in X-ray fluorescence devices. Several cobalt compounds are oxidation catalysts. Sources of cobalt for many ocean bodies include rivers and terrestrial runoff with some input from hydrothermal vents. These proteins include methionine aminopeptidase 2, an enzyme that occurs in humans and other mammals that does not use the corrin ring of B12, but binds cobalt directly. Typical catalysts are the cobalt carboxylates (known as cobalt soaps). [112][113] In September 2020, Tesla outlined their plans to make their own, cobalt-free battery cells.[114]. Für nähere Informationen zur Nutzung Ihrer Daten lesen Sie bitte unsere Datenschutzerklärung und Cookie-Richtlinie. [124][125], Cobalt-60 has a radioactive half-life of 5.27 years. The percent composition of a compound can be measured experimentally, and these values can be used to determine the empirical formula of a compound. Step 1: Data given Predict the element that will have the highest mass percent composition in each compound without doing any calculations. Examples: Fe, Au, Co, Br, C, O, N, F. [146][147], Furthermore, cobalt metal is suspected of causing cancer (i.e., possibly carcinogenic, IARC Group 2B) as per the International Agency for Research on Cancer (IARC) Monographs. [11], The United States Geological Survey estimates world reserves of cobalt at 7,100,000 metric tons. [61][62] The temperature stability of these alloys makes them suitable for turbine blades for gas turbines and aircraft jet engines, although nickel-based single-crystal alloys surpass them in performance. In 2016, 116,000 tonnes of cobalt was used. ** The percent composition: is the percent by mass of each element in a compound. It will calculate the total mass along with the elemental composition and mass of each element in the compound. [129], Cobalt is essential to the metabolism of all animals. Formerly Shaba province, the area had almost 40% of global reserves, reported the British Geological Survey in 2009. First find the molar masses of all of the compounds: SrCl2 = 158.53g/mol SrI2 = 341.43g/mol SrO = 103.62g/mol SrS = 119.68g/mo Then find the molar mass of Sr in each of the compounds. (Determined by multiplying the subscripts of … This industry has increased five-fold in its demand for cobalt, which makes it urgent to find new raw materials in more stable areas of the world. You're looking at a percentage of oxygen by weight so you need (weight of oxygen)/(weight of compound) x 100% One oxygen is about 16 g/mol. In addition they are used as accelerators in polyester resin systems. It is a key constituent of cobalamin, also known as vitamin B12, the primary biological reservoir of cobalt as an ultratrace element. The special alloys of aluminium, nickel, cobalt and iron, known as Alnico, and of samarium and cobalt (samarium-cobalt magnet) are used in permanent magnets. The Curie temperature is 1,115 °C (2,039 °F) and the magnetic moment is 1.6–1.7 Bohr magnetons per atom. Coenzyme B12 features a reactive C-Co bond that participates in the reactions. This instability affected the price of cobalt and also created perverse incentives for the combatants in the First and Second Congo Wars to prolong the fighting, since access to diamond mines and other valuable resources helped to finance their military goals—which frequently amounted to genocide—and also enriched the fighters themselves. Methylmalonyl coenzyme A mutase (MUT) converts MMl-CoA to Su-CoA, an important step in the extraction of energy from proteins and fats. Mg is the lightest of all of the 2A elements you listed. Dissolved cobalt (dCo) concentrations across oceans are controlled primarily by reservoirs where dissolved oxygen concentrations are low. share. 13.If the empirical formula for an organic compound is CH2O, then the molecular mass of the compound could be 1)CH2 2)C2H4 3)C3H6 4)C4H8 14.A compound has an empirical formula of CH2 and a molecular mass of 56. report. Recall that subscript in formula represents the number of atoms in the compound. This process helps to clean petroleum of sulfur impurities that interfere with the refining of liquid fuels.[94]. Cobalt-based superalloys have historically consumed most of the cobalt produced. 61% Upvoted. [91] Some high-speed steels also contain cobalt for increased heat and wear resistance. Vom Bürger Thenard", "Ciudad Juarez orphaned source dispersal, 1983", "Field portable XRF analysis of environmental samples", Australian Academy of Science > Deceased Fellows > Hedley Ralph Marston 1900–1965, "Cobalt : its use to control wasting disease", "Nickel, chromium and cobalt in consumer products: revisiting safe levels in the new millennium", "Role of cobalt, iron, lead, manganese, mercury, platinum, selenium, and titanium in carcinogenesis", Centers for Disease and Prevention – Cobalt, https://en.wikipedia.org/w/index.php?title=Cobalt&oldid=997496642, Biology and pharmacology of chemical elements, Extractive Industries Transparency Initiative, Short description is different from Wikidata, Articles with unsourced statements from October 2019, Wikipedia articles needing clarification from March 2018, Creative Commons Attribution-ShareAlike License, It is also used as a base primer coat for, This page was last edited on 31 December 2020, at 20:08. [clarification needed][141][140][142], Cobalt is an essential element for life in minute amounts. Feb 11 2012 12:33 PM. Cobalt-60 (Co-60 or 60Co) is useful as a gamma-ray source because it can be produced in predictable amounts with high activity by bombarding cobalt with neutrons. H2CO3: 12 / 62 = 0.19. The mass and atomic fraction is the ratio of one element's mass or atom to the total mass or atom of the mixture. MgS. Alloys with chromium and tungsten carbides are very hard and wear-resistant. [133][134] Bacteria in the stomachs of ruminant animals convert cobalt salts into vitamin B12, a compound which can only be produced by bacteria or archaea. [144] In the US, the Occupational Safety and Health Administration (OSHA) has designated a permissible exposure limit (PEL) in the workplace as a time-weighted average (TWA) of 0.1 mg/m3. You decompose a compound containing nitrogen and oxygen in the laboratory and produce 24.5g of nitrogen and 70.0g of oxygen. weld integrity radiographs), density measurements (e.g. The answer is (3) SrO.The number of Sr is the same so if the compound has the smallest gram formula mass, it has the highest percent composition by mass of strontium. [145], However, chronic cobalt ingestion has caused serious health problems at doses far less than the lethal dose. [92] It is also alloyed with 95% platinum for jewelry, yielding an alloy suitable for fine casting, which is also slightly magnetic. This oxide is reduced to metal by the aluminothermic reaction or reduction with carbon in a blast furnace. [A] HCl [B] H 2 S [C] HF [D] H 2 SO 4 [E] H 2 O . Cobalt is a ferromagnetic metal with a specific gravity of 8.9. Cobalt extracted from small Congolese artisanal mining endeavors in 2007 supplied a single Chinese company, Congo DongFang International Mining. This market share may reach 73% by 2025 if planned expansions by mining producers like Glencore Plc take place as expected. Yahoo ist Teil von Verizon Media. This program determines the molecular mass of a substance. [61][62] It can also be used to make rechargeable batteries, and the advent of electric vehicles and their success with consumers probably has a great deal to do with the DRC's soaring production. What is the value of n necessary to find the molecular formula? The cobalt deficiency was overcome by the development of "cobalt bullets", dense pellets of cobalt oxide mixed with clay given orally for lodging in the animal's rumen. You know that Carbon weighs approximately 12, Hydrogen weight aproximately 1, oxygen … [80], In February 2018, global asset management firm AllianceBernstein defined the DRC as economically "the Saudi Arabia of the electric vehicle age," due to its cobalt resources, as essential to the lithium-ion batteries that drive electric vehicles. [90] Cobalt alloys are also used for dental prosthetics as a useful substitute for nickel, which may be allergenic. In 2017, some exploration companies were planning to survey old silver and cobalt mines in the area of Cobalt, Ontario where significant deposits are believed to lie. The material is composed of cobalt oxide layers with the lithium intercalated. Which compound has the highest mass percent of O? Methyl alcohol also called methanol which is CH3OH. Use uppercase for the first character in the element and lowercase for the second character. [50][51] The Co-containing complex cobalamin is only synthesized by cyanobacteria and a few archaea, so dissolved cobalt concentrations are low in the upper ocean. [46][47], Cobalt is also a constituent of tobacco smoke. [100] Exploration in 2016–2017 included the area around Cobalt, Ontario, an area where many silver mines ceased operation decades ago. Damit Verizon Media und unsere Partner Ihre personenbezogenen Daten verarbeiten können, wählen Sie bitte 'Ich stimme zu.' O. The lack of safety precautions frequently causes injuries or death. The Mukondo Mountain project, operated by the Central African Mining and Exploration Company (CAMEC) in Katanga Province, may be the richest cobalt reserve in the world. [97], Although in 2018 most cobalt in batteries was used in a mobile device,[98] a more recent application for cobalt is rechargeable batteries for electric cars. [110][111] As of August 2020 battery makers have gradually reduced the cathode cobalt content from 1/3 (NMC 111) to 2/10 (NMC 442) to currently 1/10 (NMC 811) and have also introduced the cobalt free LFP cathode into the battery packs of electric cars such as the Tesla Model 3.
