What volume of hydrogen can be obtained by the action of 0.2 mol of zinc on a sulfate acid solution?

When zinc metal is dissolved in acid, hydrogen gas is released. In this case, regardless of which acid is used, 1 mol of hydrogen is released per 1 mol of dissolved zinc.

N Zn = 0.2 mol;

The same amount of hydrogen will be released.

Let’s calculate its volume. To do this, multiply the amount of substance by the volume of 1 mole of gas (22.4 liters).

V H2 = 0.2 x 22.4 = 4.48 liters;
