Determine the volume of gas released as a result of the interaction of 20 g of zinc with concentrated 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 20 grams of zinc.

M Zn = 65 grams / mol;

N Zn = 20/65 = 0.3077 mol;

The same amount of hydrogen gas will be released.

1 mole of ideal gas normally takes on a volume of 22.40 liters.

The volume of hydrogen will be:

V H2 = 0.3077 x 22.40 = 6.89 liters;
