Calculate how many grams of zinc reacted with sulfuric acid, if you get 5.6 liters hydrogen?

The reaction proceeds according to the following chemical reaction equation:

Zn + H2SO4 = ZnSO4 + H2;

Let’s find the chemical amount of hydrogen. For this purpose, we divide its volume by the volume of 1 mole of gas (22.4 liters)

N H2 = 5.6 / 22.4 = 0.25 mol;

To obtain such an amount of hydrogen, 0.25 mol of zinc must be dissolved in acid.

Let’s calculate its weight.

To do this, multiply the amount of substance by weight

M Zn = 65 grams / mol;

m Zn = 0.25 x 65 = 16.25 grams;
