Answer to Question #90663 in General Chemistry for saima

Question

if 16.02g mass of copper (ii) oxide is required to produce 12.8g of copper then what mass of carbon dioxide is produced?

Answer 1

2CuO + C = CO₂ + 2Cu

m (CuO) = 16.02 g

2 mol

Mr = 80 g/mol

m = 160 g

m (CO₂) - ?

1 mol

Mr = 46 g/mol

m = 46 g

m (CO₂) is produced = 4.6 g
