Vapour density of a gas is 22. Its molecular mass will be:a)33g...
Calculating Molecular Mass from Vapour Density
Vapour density is the ratio of the molecular mass of a gas to its density. It is denoted by the symbol 'D'. We can calculate the molecular mass of a gas using the formula:
Molecular mass = 2 × Vapour density
Here, the molecular mass is expressed in grams per mole (g/mol).
Given that the vapour density of a gas is 22, we can calculate its molecular mass as follows:
Molecular mass = 2 × Vapour density
= 2 × 22
= 44 g/mol
Therefore, the correct answer is option 'B', which states that the molecular mass of the gas is 44 g.
