The ratio of the rate of diffusion of a given element to that of helium at the same pressure is 1.4. The molecular weight of the element is

A gas diffuses at a rate which is twice that of another gas B. The ratio of molecular weights of A to B is

The rate of diffusion of a gas is proportional to

The rate of diffusion of methane is twice that of X . The molecular mass of X is divided by 32 . What is value of x is ?

50 mL of a gas A diffuse through a membrane in the same time as for the diffusion of 40 mL of a gas B under identical pressure temperature conditions. If the molecular weight of A = 64 that of B would be

Two separate bulbs contains ideal gases P and q, respectively maintained at the same temperature. The density of gas P is twice of that of the Q, and the molecular weight of the gas P is half of that of the gas Q. The ratio of the pressure of gas P to that of gas Q is

The rate of diffusion of a gas X is sqrt(2) times that of Y. If the molecular mass X is 16, what is the molecular mass of gas y?
