1. The reaction of zinc with hydrochloric acid proceeds according to the equation:

Zn + 2HCl = ZnCl2 + H2 ↑;

2.Calculate the chemical amount of reacting zinc:

n (Zn) = m (Zn): M (Zn) = 26: 65 = 0.4 mol;

3. Determine the amount and calculate the volume of released hydrogen:

n (H2) = n (Zn) = 0.4 mol;

V (H2) = n (H2) * Vm = 0.4 * 22.4 = 8.96 liters.

Answer: 8.96 liters.
