Question

Rate of diffusion of ch4 at a given temperature is twice that of gas x the molecular mass of x is

Answer 1

Answer:

64

Explanation:

rate of diffusion is inversely proportional to square root of molecular mass.       after applying this formula r is inversely proportional to MOLECULAR MASS^1/2 we will get molar mass of unknown gas has 64grams

Answer 2

Explanation:

rate of diffusion of ch4 / rate of diffusion of gas x =

$\sqrt{mass \: of \: x} \div \sqrt{mass \: of \: ch4}$

x/16=4

x=64
