How much hydrogen will displace 130 g of zinc from the hydrochloric acid HCl solution?

How much hydrogen will displace 130 g of zinc from the hydrochloric acid HCl solution? As a result of the reaction, in addition to hydrogen, a substance zinc chloride ZnCl2 is formed.

If granules of metallic zinc are placed in hydrochloric acid, hydrogen will start to evolve.

Zn + 2HCl → ZnCl2 + H2;

The chemical amount of hydrogen will be equal to the chemical amount of the metal taken.

Let’s determine the molar amount of zinc.

M Zn = 65 grams / mol;

N Zn = 130/65 = 2.0 mol;

The same amount of hydrogen will be synthesized.

Find the volume of 2 mol of hydrogen. Let’s multiply its quantity by the volume of 1 mole of gas.

V H2 = 22.4 x 2 = 44.8 liters;
