a sample of hydrogen effuses through a porous container about 9 times faster than an unknown gas. Estimate the molar mass of the unknown gas.

rateH2/rateunk = sqrt (M unk)/MH2)
The problem doesn't give a rate; therefore, choose a convenient number, such as 1L/1 sec for H2 which makes the unknown 1L/9 sec since it is 9 times slower.
