Question

Molecular weight is equal to 2× vapour density give reason

Answer 1

Answer:

V.D = M.M / 2 ( V.D - Vapour density, M.M - Molar mass )

Explanation:

Actually Vapour density of a gas is the ratio of densities of gas & hydrogen at the same temperature & pressure.

V.D = Density of gas at some P & T / Density of Hydrogen at same P & T
