Part 1:

Calculate the diffusivity of hydrogen in air at 1 atm and 298 K from values for hydrogen-oxygen and hydrogen-nitrogen. Assume that air is 21% oxygen and 79% nitrogen. Correct for temperature as required by assuming that diffusivity is proportion to T^1.5

There is a part 2 posted separately, so you can get credit for both parts :)

Thank you!
