What volume of hydrogen is formed when 260 g of zinc are dissolved in hydrochloric acid?

1. When zinc dissolves in hydrochloric acid, the following reaction occurs:

Zn + 2HCl = ZnCl2 + H2 ↑;

2.Calculate the chemical amount of zinc:

n (Zn) = m (Zn): M (Zn) = 260: 65 = 4 mol;

3. Determine the amount of generated hydrogen:

n (H2) = n (Zn) = 4 mol;

4. find the volume of hydrogen:

V (H2) = n (H2) * Vm = 4 * 24.4 = 89.6 liters.

Answer: 89.6 liters.
