The vapour density of gas A is four times that of B. If moelcular mass of B is M, then molecular mass of A is

The density of a gas A is three times that of a gas B. It the molecular mass of A is M, the molecular mass of B is

If the density of a gas A is 1.5 times that of B, then the molecular mass of A is M. The molecular mass of B will be

If the density of a gas A is 1.5 times that of B, then the molecular mass of A is M. The molecular mass of B will be

The vapour density of a gas A is twice that of a gas B. If the molecular weight of B is M, the molecular weight of A will be:

The ratio of density of a gas A and gas B is three. If the molecular mass of A is M, then molecular mass of B is

The ratio of density of a gas A and gas B is three. If the molecular mass of A is M, then molecular mass of B is

Under identical conditions of temperature the density of a gas A is three times that of gas B while molecular mass of gas B while molecular mass of gas B is twice that of A. The ratio of pressure of A and B will be :
