The mass of zinc consumed to obtain 6 mol of hydrogen when interacting with hydrochloric acid is …

Zinc reacts violently with hydrochloric acid to release hydrogen gas and form zinc chloride. The reaction is described by the following equation:

Zn + 2HCl = ZnCl2 + H2;

1 mole of metal reacts with 2 moles of acid. This synthesizes 1 mol of salt and 1 mol of hydrogen.

To synthesize such an amount of hydrogen, it is necessary to take the same amount of zinc. Let’s calculate its weight. To do this, we multiply the amount of substance by the weight of 1 mole of metallic zinc.

M Zn = 65 grams / mol;

N Zn = 6 mol;

m Zn = 6 x 65 = 390 grams;
