The densities of two gases, X and Y, are 0.5 g dm^-3 and 2.0 dm^-3 respectively.
What is the rate of diffusion of X relative to Y?

R =1/✔D

Dx = 0.5

Dy= 2.0

Rx/Ry = ✔Dy/✔Dx

✔2.0/✔0.5

= 2

So, C is correct

Rate of diffusion of X =Rx
Rate of diffusion of Y is Ry
Density of x is 0.5
Density of Y is 2
Using the formula

Rx/Ry=√Density of y/√Density of X
Rx/Ry=√2/√0.5
where 0.5 is 1/2
Rx/Ry=√2/√1/2 =√2/(1/2
Rx/Ry=√2/1×2/1
Rx/Ry=√4
Rx/Ry=2

Thanks
