What volume of hydrogen can be obtained by the action of hydrochloric acid HCl

What volume of hydrogen can be obtained by the action of hydrochloric acid HCl on zinc with a chemical amount of 0.5 mol?

Zinc reacts intensively with hydrochloric acid according to the following scheme:

Zn + 2HCl → ZnCl2 + H2;

The reaction requires double the amount of acid. In this case, 1 hydrogen molecule is formed from the spirit of acid molecules.

N Zn = 0.5 mol;

Let us determine the volume of 0.5 mol of hydrogen. Let’s multiply its quantity by the volume of 1 mole of ideal gas:

V H2 = 22.4 x 0.5 = 11.2 liters;
