Zinc dissolves in hydrochloric acid, the reaction proceeds according to the following chemical equation:
Zn + 2HCl = ZnCl2 + H2;
Let’s calculate the molar amount of synthesized hydrogen.
For this purpose, we divide the volume that it occupies by the volume of 1 mole of gas (filling the space with 22.4 liters).
N H2 = 32 / 22.4 = 1.43 mol;
The same amount of zinc chloride will be synthesized.
Let’s calculate its mass.
To do this, multiply the amount of the substance by its molar weight.
M ZnCl2 = 65 + 35.5 x 2 = 136 grams / mol;
m ZnCl2 = 1.43 x 136 = 194.48 grams;
