Determine the number of hydrogen molecules that will be released during the interaction of 1.3 g

Determine the number of hydrogen molecules that will be released during the interaction of 1.3 g of zinc with sulfuric acid

The reaction between zinc metal and sulfuric acid is described by the following chemical equation:

Zn + H2SO4 = ZnSO4 + H2;

When 1 molecule of zinc dissolves, 1 molecule of hydrogen is released.

Let’s calculate the chemical amount of a substance in 1.3 grams of zinc.

M Zn = 65 grams / mol;

N Zn = 1.3 / 65 = 0.02 mol;

The same amount of hydrogen gas will be released.

1 mole of a substance contains 6.022 x 10 ^ 23 molecules.

The number of hydrogen molecules will be:

K = 0.02 x 6.022 x 10 ^ 23 = 1.2044 x 10 ^ 22 molecules.
