Question

Ratio of rate of diffusion of two gases is 1 is to 4 and then the ratio of their molecular weight is

Answer 1

Answer:

Apply Graham's law, the rate of diffusion is inversely proportional to square root of molecular mass. This means ratio of their molecular weight will be = 16:1

Answer 2

Answer:

We know that,

Rate of diffusion is inversely proportional to the square root of molecular weight .

r1: r2= (m2/ m1)^1/2

= (1/4)^2= (m2/m1)

m2 /m1 = 1/ 16

Thus , m1/ m2 = 16
