Explanation:
Balance reaction:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
185 g Fe₂O₃ × 1 mol Fe₂O₃/ 159.69 g Fe₂O₃ × 3 mole CO/ 1 mole Fe₂O₃ × 28 g / 1 mol CO =
= 1.15 × 3 × 28
= 96.6 g of CO since we have 95.8, Fe₂O₃ is the limiting agent.
185 g Fe₂O₃ × 1 mol Fe₂O₃/ 159.69 g Fe₂O₃ × 2 mole Fe / 1 mole Fe₂O₃ × 55.84 g / 1 mol Fe =
= 1.15 × 2 × 55.84
=128.43 g of Fe
Theorectical yield
185 g Fe₂O₃ ⇒ 87.4 g of Fe
If 87.4 g of Fe is formed in the reaction then the % yield will be
= 87.4 g of Fe/128.43 g of Fe × 100
= 68.05 %
