When a 10 g sample of copper oxide is reduced by heating in the presence of carbon monoxide, how many moles of copper are formed?

1 answer

how many mols of copper oxide (CuO) in 10 grams?
Cu = 63.5
O = 16
CuO = 79.5 grams/mol
so we have
10 grams / 79.5 g/mol = .126 mols of CuO
same number of mols of Cu
