1. Let’s find the molar mass of the hydrogen molecule.
Мr (Н2) = 1 * 2 = 2 g / mol
2. Let’s find the amount of substance contained in 3 g of hydrogen.
M = m / Mr = 3/2 = 1.5 mol
3. Let’s calculate the volume of hydrogen. Molar volume (Vm) is a constant value equal to 22.4 l / mol.
V = M * Vm = 1.5 * 22.4 = 33.6 liters of hydrogen
