Question

Relationship between molecular mass and vapour density

Answer 1

Answer:

Molecular mass = 2 × vapour density

Explanation:

It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapour density = mass of n molecules of gas / mass of n molecules of hydrogen. (and thus: molar mass = ~2 × vapour density) For example, vapour density of mixture of NO2 and N2O4 is 38.
