What volume will 0.2 mole of hydrogen gas take?

To find the volume occupied by the taken hydrogen, we apply the formula: ν = V (H2) / Vm, whence we express: V (H2) = ν * Vm.

Const: Vm – molar volume (Vm = 22.4 l / mol).

Problem data: ν – amount of the substance taken hydrogen (ν = 0.2 mol).

Let’s make a calculation: V (H2) = ν * Vm = 0.2 * 22.4 = 4.48 liters.

Answer: Hydrogen in the amount of a substance of 0.2 mol will occupy a volume equal to 4.48 liters.
