Question

calculate the mass of aron in 10kg of Fe2O3 RAM is 56 of Fe.​

Answer 1

Explanation:

Ferric oxide = iron(III) oxide = Fe2O3

molar mass Fe2O3 = 159.69 g/mol

molar mass Fe = 55.845 g/mol

10 kg × 0.8 Fe2O3 = 80 kg Fe2O3

80 kg Fe2O3 × (1 mol Fe2O3/159.69 g Fe2O3) × (2 mol Fe/1 mol Fe2O3) × (55.845 g Fe/1 mol Fe) = 55.953 kg
