1. The mass of Fe2O3 required will be 51.29 grams
2. The mass of Cu that will be formed is 36 kg
<h3>Stoichiometric problems</h3>1) The equation of the reaction goes thus:
Mole ratio of Fe to Fe2O3 = 2:1
Mole of 35.9 g Fe = 35.9/56 = 0.6411 mol
Equivalent mole of Fe2O3 = 0.6411/2 = 0.3205 mol
Mass of 0.3205 mol Fe2O3 = 0.3205 x 160 = 51.29 grams
2)
Mole ratio of CuO to Cu = 1:1
Mole of 45 kg CuO = 45000/80 = 562.5 mol
Equivalent mole of Cy = 562.5 mol
Mass of 562.5 mol of Cu = 562.5 x 64 = 36,000 grams or 36 kg
