or:Copper carbonateFrom Wikipedia, the free encyclopediaCopper carbonate generally means a compound containing copper and carbonate ions. It may be any of several substances: basic copper carbonate (the \"copper carbonate\" of commerce), actually a copper carbonate hydroxide; which may be either Cu2CO3(OH)2: the green mineral malachite, and the pigment \"verditer\" or \"mountain green\" Cu3(CO3)2(OH)2: the blue mineral azurite, and the pigment \"blue verditer\" or \"mountain blue\" or a mixture of the two. copper(II) carbonate proper, CuCO3 (neutral copper carbonate): a rarely seen moisture-sensitive compound.(end quote)So the question is ambiguous. This is simple arithmetic and you need to learn it perfectly to be any good in chemistry. You do have a printed periodic table, right? You can get the information at www.chemicalelements.com/index.html but you really need your own printed copy to carry with you. It will be a primary reference for everything you do. There is a diagonal line, B-C, Si-P, Ge-As, Sb-Te, and Po-At. Elements to the left of the line are metals, meaning they lose an electron easily, elements to the right of the line are non-metals, and elements on the line are semiconductors.Assuming CuCO3:Cu - 58.6934 atomic massC - 12.011O - 15.9994 x 3 = 47.9982--------------------- ADDtotal - 118.7026 mass(grams) of a mole of CuCO3You are given 8.4/118.7026 = 0.0708 mole. Now you see the beauty of the mole system: CuCO3 -> CuO + CO2 -- That means one mole of copper carbonate yields one mole of CO2. So compute the mass of a mole of CO2 as I demonstrated above and your answer is 0.0708 times that number.
