If 4 g O_(2) effuse through a very narrow hole , How much H_(2) would have effused under identical conditions .

The molecular weight of a gas which diffuses through a porous plug of 1/6th of the speed of hydrogen under identical conditions is :

50 mL of a gas A diffuse through a membrane in the same time as for the diffusion of 40 mL of gas B under identical conditions of pressure and temperature. If the molecular mass of A is 128, that of B would be :

The molecular weight of a gas which diffuses through a porous plug at 1//6^(th) of the speed of hydrogen under identical condition is:
