Question

For the reaction: Fe₂O₃ + 3CO → 2Fe + 3CO₂, how many kg of Fe is produced from 160 kg of Fe₂O₃? (Fe = 56, O = 16)
  1. A
    56 kg
  2. B
    112 kg
    Correct
  3. C
    168 kg
  4. D
    224 kg

Correct answer

112 kg

Explanation

M(Fe₂O₃) = 160 g/mol. 160 kg / 160 g/mol = 1000 mol Fe₂O₃. Each mol gives 2 mol Fe → 2000 mol Fe. Mass = 2000 × 56 g = 112,000 g = 112 kg.
