Question

The rate of diffusion of methane at A given temperature is twice that of A gas the molecular weight of the gas will be

Answer 1

Answer:64

Explanation:rate of diffusion of gas is inversely proportional to start of molecular mass .

Molecular mass of CH4=16

Molecular mass of x=?

Rate of diffusion of CH4/rate of diffusion of X=√x/√16

2×rate of diffusion of X/rate of diffusion of X=√x/√16

4=x/16

X=64
