Based on the mass ratio, the mass of H₂ produced is 3.51 g of H₂
The mass ratio of a reaction is the ratio of the masses of the reactants as well as as products in a balanced equation of a reaction.
The equation of the reaction is given below;
2 AI + 6 HCI → 2 AICI₃ + 3 H₂
From the reaction equation, 2 * 27 g of Al produces 3 * 2 g of H₂
32.25 g of Al will produce: 6/55 * 32.25 g of H₂
Therefore, mass of H₂ produced is 3.51 g of H₂
