1) M (Cl₂) = 2Ar (Cl) = 2 * 35.5 = 71 г/моль
n = m / M = 71 / 71 = 1 моль
V = n * Vm = 1 * 22.4 = 22.4 л
2) M (N₂) = 2Ar (N) = 2 * 14 = 28 г/моль
n = m / M = 1.4 / 28 = 0.05 моль
V = n * Vm = 0.05 * 22.4 = 1.12 л
3) M (SO₂) = Ar (S) + 2Ar (O) = 32 + 2 * 16 = 64 г/моль
n = m / M = 6.4 / 64 = 0.1 моль
V = n * Vm = 0.1 * 22.4 = 2.24 л
4) M (CO) = Ar (C) + Ar (O) = 12 + 16 = 28 г/моль
n = m / M = 5.6 / 28 = 0.2 моль
V = n * Vm = 0.2 * 22.4 = 4.48 л
