" If the ratio of the rates of diffusion of the two gases 'A' and 'B' is 4:1,the ratio of their densities 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 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, then what is the ratio of densities of B and A ?

Under the same conditions the rates of diffusion of two gases are in the ratio 1:4. The ratio of their vapour densities is

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

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.

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