Question

How much faster does H2 travel than Ar gas?

Answer 1

Won't do your homework, but here is how to do it.

Graham's Law of Effusion/Diffusion (look it up and read about it)

rate of gas 1 / rate of gas 2 = sqrt MW gas 2 / sqrt MW gas 1

MW H₂ = 2

MW Ar = 40

rate H₂/rate Ar = √ 40/2 = how much faster H2 will move compared to Ar
