Vapour density of a volatile substance is

(\mathrm{C}{\mathrm{H}_4} = \mathrm{ }1\mathrm{ })

. Its molecular weight would be:

View answer and explanation

Correct option: C

Option C (64) is correct because the molecular weight is twice the vapor density, and the vapor density is given relative to methane (CH4 = 1).
