The volume of hydrogen released during the interaction of zinc with a solution containing 9.8 g. sulfuric acid is …

When zinc reacts with hydrogen, the chemical amount of hydrogen produced will be equal to the chemical amount of the acid that has reacted:
Zn + H2SO4 → ZnSO4 + H2;
Let’s find the chemical amount of sulfuric acid.
M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol;
N H2SO4 = 9.8 / 98 = 0.1 mol;
With this amount of zinc and acid, it is possible to obtain 0.1 mol of hydrogen.
Let’s calculate the volume of 0.1 mol of hydrogen.
V H2 = 22.4 x 0.1 = 2.24 liters;
