1. Let’s write the reaction equation:
Mg + 2HCl = MgCl2 + H2 ↑;
2.Calculate the chemical amount of magnesium:
n (Mg) = m (Mg): M (Mg) = 12: 24 = 0.5 mol;
3.Calculate the amount and volume of the generated hydrogen:
n (H2) = n (Mg) = 0.5 mol;
V (H2) = n (H2) * Vm = 0.5 * 22.4 = 11.2 liters.
Answer: 0.5 mol; 11.2 l.
