Calculate the mass of salt that can be obtained if 6.5 g. Dissolve zinc in sulfuric acid solution.

Zinc metal reacts with sulfuric acid to release hydrogen gas and form zinc sulfate. The reaction is described by the following equation:

Zn + H2SO4 = ZnSO4 + H2;

1 mole of metal reacts with 1 mole of acid. This synthesizes 1 mol of salt and 1 mol of hydrogen.

Let’s calculate the amount of zinc.

M Zn = 65 grams / mol;

N Zn = 6.5 / 65 = 0.1 mol;

The same amount of zinc sulfate will be synthesized. Let’s calculate its weight.

M ZnSO4 = 65 + 32 + 16 x 4 = 161 grams / mol;

m ZnSO4 = 0.1 x 161 = 16.1 grams;
