Question

Write the relation between molecular mass and vapour density

Answer 1

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.

Answer 2

Concept introduction:

Relative molecular mass of an object to that of hydrogen gas is known as vapor density.

Explanation:

Given that, we need to find how molecular mass is related to vapor density.

We have to find, relation between molecular mass and vapor density.

According to the question, vapor density = molecular mass of n molecules of gas ÷ molecular mass of n molecule of hydrogen gas. Hence, vapor density = molecular mass ÷ $2$

Final Answer:

Relation between vapor density and molecular mass is, Vapor density = Molecular mass ÷ $2$
