Concept: Graham's Law of Effusion
Use the graham's law of effusion equation to find molar mass of unknown gas.
First will have to find the rate of effusion of each, since only times are given.
We will assume that we have 1 L of each gas, however you can pick any value for volume, as long as the two volumes are the same for both gases.
A sample of an unknown gas effuses in 11.1 min. An equal volume of H 2 in the same apparatus under the same conditions effuses in 2.42 min. What is the molar mass of the unknown gas?
