There is an intermediate value between mass and volume – the amount of a substance (measured in moles).

1. Let’s convert grams into moles by the formula: n = m / M

M (N2) = 14 * 2 = 28 g / mol

n (N2) = 112/28 = 4 mol

2. We convert moles to liters according to the formula: V = n * Vm (Vm – constant = 22.4 l / mol)

V (N2) = 4 * 22.4 = 89.6 l.
