Ответ:
223.4 g of iron can be formed from 6 moles of hydrogen gas.
Explanation:
Fe₂O₃(s) + 3 H₂(g) → 2 Fe(s) + 3 H₂O(l)
Since the given equation is the balanced one, we need 3 moles of hydrogen gas to make 2 moles of iron, so the molar ratio is 3:2. So, from 6 moles of hydrogen gas, we can make few moles of iron as,
Molar mass of iron = 55.85 g
So amount of iron produced = 4 moles × 55.85 g/mol = 223.4 g of iron
