How many moles of carbon dioxide would be produced if 25 g of copper carbonate were completely decomposed by heating?
CuCO3 ==> CuO + CO2
1.mols CuCO3 = grams/molar mass
2.Use the coefficients in the balanced equation to convert mols CuCO3 to mols CO2.
3. Now convert mols CO2 to grams. g = mols x molar mass.
