From Wikipedia, the free encyclopedia. Vapor density is the density of a vapour in relation to that of hydrogen. It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapor density = mass of n molecules of gas / mass of n molecules of hydrogen. Therefore: vapour density = molar mass of gas / molar mass of H 2.
density is the mass per unit volume. This means that the density of any solid, liquid or gas can be found by dividing it's mass in kilograms by it's volume in cubic metres.he formula for density is. Density = mass/volume. So something that is very heavy but doesn't take up much space is considered to have a high density (like lead), but something that is light and takes up a lot of space has a low density (like feathers).
