The mass of zinc is 73 grams, it reacted with h2so4. Find the volume of hydrogen.

In sulfuric acid, zinc dissolves in the same proportions:

Zn + H2SO4 → ZnSO4 + H2;

The amount of hydrogen is equal to the amount of zinc.

Find the molar amount of zinc.

M Zn = 65 grams / mol;

N Zn = 73/65 = 1.123 mol;

With this amount of zinc, it is possible to obtain 1.123 mol of hydrogen.

Knowing the volume of 1 mole of an ideal gas, we find the volume of hydrogen:

V H2 = 22.4 x 1.123 = 25.155 liters;
