Under normal conditions, how much will the hydrogen produced by the reaction of 13 grams

Under normal conditions, how much will the hydrogen produced by the reaction of 13 grams of zinc with hydrochloric acid take?

When dissolved in hydrochloric acid, metallic zinc is converted to zinc chloride. The reaction is described by the following chemical reaction equation:

Zn + 2HCl = ZnCl2 + H2;

Let’s find the molar amount of metallic zinc. To do this, we divide its weight by the mass of 1 mole of metal.

N Zn = 13/65 = 0.2 mol;

With this amount of zinc, 0.4 mol of acid reacts. This will synthesize 0.2 mol of hydrogen. Let’s calculate its volume. To do this, multiply the amount of substance by the volume of 1 mole of gas (which is 22.4 liters).

V H2 = 0.2 x 22.4 = 4.48 liters;
