What volume of gas will be released when dissolved in an excess of zinc hydrochloric acid, weight 1.3?

During this chemical reaction, zinc metal is converted to a zinc chloride salt. Zinc is a bivalent metal. Therefore, during the reaction, it interacts with a double amount of hydrochloric acid. A single chemical amount of zinc chloride is synthesized. The reaction is described by the following chemical reaction equation:

Zn + 2HCl = ZnCl2 + H2;

Let’s determine the chemical amount of zinc. For this purpose, we divide its weight by the mass of 1 mole of metal.

N Zn = 1.3 / 65 = 0.02 mol;

With this amount of zinc, 0.04 mol of acid reacts. This will synthesize 0.02 mol of hydrogen. Let’s find 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 = 0.02 x 22.4 = 0.448 liters;
