WebFrom the balanced chemical equation above, we can see that 1 mole of Al reacts with 1/2 mole of H2. Therefore, to determine the number of moles of H2 formed by the complete reaction of 0.325 mol of Al, we can use the following calculation: 0.325 mol Al × (1/2 mol H2 / 1 mol Al) = 0.163 mol H2 Answer: 0.163 mol H2
