Question

How to calculate the vapour density of a mixture?

Answer 1

It may be defined as mass of a certain volume of a substance divided by mass of samevolume 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.

Answer 2

vapour density = mass of n molecules of gas / mass of n molecules of hydrogen.
using this formula we can calculate vapour density
