Compute the relative rate of diffusion of argon to helium. Would I use Grahams Law for this problem?

    the wording says Ar to He, which is interpreted as Ar:He or \(\dfrac{Ar}{He}\). you wrote it in reverse

    Oh I didn't think I had. Thank you. One last question, sorry, the numbers I have for them are correct right, I am supposed to use there mass?

    yep, uppercase \(M\) stands for molar mass

    how do you find or calculate the units?

    there are no units, because you're comparing 2 different rates. The answer you get is the \(factor\) that argon diffuses at relative to helium

    if the answer you get is 0.2, then argon diffuses 0.2 \(times \space as \space fast\) as helium, etc etc
