Question

Consider the following reaction occurring in the blast furnace: Fe3O4(s) + 4CO(g) 3Fe(I) + 4CO2(g) 'x' kg of iron is produced when 2.32 × 103 kg Fe3O4 and 2.8 × 102 kg CO are brought together in the furnace. The value of 'x' is ____________. (nearest integer) [Given: molar mass of Fe3O4 = 232 g mol–1, molar mass of CO = 28 g mol–1, molar mass of Fe = 56 g mol–1]

Answer: .

💡 Solution & Explanation

Fe3O4 + 4 CO  3Fe + 4CO2 ni 10000 (LR) nf 10000 × 3 = 7500  WFe = 7500 × 56 g = 420 kg
