How much hydrogen will be released when zinc interacts with sulfate acid weighing 49g?

If necessary, to obtain hydrogen under laboratory conditions, zinc is dissolved in sulfuric acid. The following reaction is going on:

Zn + H2SO4 → ZnSO4 + H2;

Substances react in the same molar ratios:

Let’s determine the chemical amount of sulfuric acid.

M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol;

N H2SO4 = 49/98 = 0.5 mol;

The same amount of hydrogen will be produced.

Let’s find the volume its volume:

V H2 = 22.4 x 0.5 = 11.2 liters;
