Determine the density of chlorine relative to hydrogen and helium.

The atomic mass of chlorine (Cl) is 35.5 g / mol. Since the gas is diatomic, the relative molecular weight of chlorine is: Мr = 35.5 * 2 = 71 g / mol.
The relative density of chlorine for hydrogen:
D (H2) = Мr (Cl) / Мr (Н2), where Мr (Н2) is the relative molecular weight of hydrogen (Мr (Н2) = 2 g / mol).
D (H2) = 71/2 = 35.5.
The relative density of chlorine for helium:
D (He) = Mr (Cl) / Mr (He), where Mr (He) is the relative molecular weight of helium (Mr (He) = 4 g / mol).
D (He) = 71/4 = 17.75.
Answer. D (H2) = 35.5, D (He) = 17.75.
