The ratio of rate of diffusion of gases A and B is `1 : 4`. If the ratio of their masses present in the mixture is `2 : 3`, what is the ratio of their mole fraction ?

The ratio of velocities of diffusion of gases A and B is 1 : 4 . If the ratio of their masses present in the mixture is 2 : 3 , calculate the ratio of their mole fractions.

If the ratio of the rates of diffusion of two gases A and B is 4:1 the ratio of their density is

If the ratio of the rates of diffusion of two gases A and B is 4:1 the ratio of their density is

If the ratio of rates of diffusion of gases are 6:4, then find the ratio of their molecular mass.

The ratio of rate of diffusion for two gases is 1 : 2 if their molecular masses :-

The ratio of rateof diffusion for two gases is 1 : 2 if their molecular masses :-
