Question

Relation between moliculare mass and
vapouts density​

Answer 1

MOLECULAR MASS= 2×VAPOUR DENSITY

Answer 2

Answer:

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 nmolecules of hydrogen. (and thus: molar mass = ~2 × vapour density) For example,vapour density of mixture of NO2 and N2O4 is 38.
