  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.
