Question

Vapour density definition and formula

Answer 1

Answer:

Vapour 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. vapour density = mass of n molecules of gas / mass of n molecules of hydrogen.

Explanation:

For example, vapour density of mixture of NO2 and N2O4 is 38.3 .Vapour density is a unit less quantity.

Answer 2

Answer: Vapor density is the density of a particular gas or vapor relative to that of hydrogen at the same pressure and temperature. vapour density = mass of x molecules of gas / mass of x molecules of hydrogen. You can also divide the mass by volume
