Explanation:
We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.
M_r: 55.85
Fe₃O₄ + 4H₂ → 3Fe + 4H₂O
n/mol: 14
1. Use the molar ratio of Fe:H₂ to calculate the moles of Fe.
2. Use the molar mass of Fe to calculate the mass of Fe
