Question

What is the relationship between vapour density and absolute density of a gas ?

Answer 1

Answer:

hello mate here is ur ans.....❤

Density is usually that of a solid or liquid. It's calculated by dividing the mass by the volume. Vapour density refers to a gas or vapour. It's a measure of the mass compared with an equal volume of hydrogen....hope it hlps❤

Answer 2

The relationship between the relative molecular mass and vapour density of gas is:-

Relative molecular mass = 2 × Vapour density.

1.Relative molecular mass:The Relative Molecular Mass of a gas or vapour is the ratio between the mass of one molecule of the gas or vapour to mass of one atom of Hydrogen.

2.Vapour Density:Vapour density is the ratio of the mass of a certain volume of a gas or vapour, to the mass of an equal volume of hydrogen, measured under the same conditions of temperature and pressure.

3.According to Avogadro's law, equal volumes­ of all gases contain equal number of molecules.

When you compare the formula of vapour density with relative molecular mass, they can be represented as V.D.

So,Relative molecular mass = 2 × Vapour density.
