dn/dt=PA(c2-c1)
dn/dt=quantity transported per time unit
P=permeability coeficient
A=the surface of contact where diffusion takes place
c2,c1=concentrations of the stuff on both sides, c2>c1

IS this what you need??

rate of diffusion = surface area x difference in concentration
length of diffusion pathway

Rate of diffusion(r) = volume of the gas diffuse/time take for diffusion

Rate of diffusion(r) = V/t

formula: rate A/rate B=sq. rt. B MM/sq. rt. A MM
want: MM unknown
know: MM 16.04 g/mol CH4

step 1: let x= rate A, CH4= rate B
step 2: plug in values and solve using formula
step 3: ANS

good luck.
