I don't want the answers, I just need to know how to go about these types of problems.

Effusion:
In a given period of time, 0.21 moles of a gas of molar mass = 26 g/mol effuses. How many moles of NH3 would effuse in the same period of time?

Diffusion:
What is the molar mass of a gas that diffuses at 20% of the rate that hydrogen diffuses?

I am so lost on how to solve problems like these with only the given. Please and thank you for you help.
