At constant volume and temperature conditions, the rates of diffusion r_(A) and r_(B) of gases A and B having densities P_(A) and P_(B) are related by the expression :

At constant volume and temperature conditions, the rates of diffusion r_(A) and r_(B) of gases A and B having densities P_(A) and P_(B) are related by the expression :

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 ?

At constant temperature and pressure, the rates of diffusion of two gases A and B are in the ratio of 1:2 . In a mixture of A and B gases if the mass ratio of A and B be 2:1, the find the mole fraction ratio of A and B in the mixture?
