Question

Quizplus · Accepted Answer

Using Avogadro's law and the molar ratio between hydrogen and iron, we can find the number of moles of iron produced:
(17.4 L H2) / (22.4 L/mol H2) * (2 mol Fe / 3 mol H2) = (17.4/22.4)(2/3) mol Fe

In the Reaction Fe2O3 + 3 H2 → 2 Fe

In the Reaction Fe₂O₃ + 3 H₂ → 2 Fe
