Compute the molar mass of the unknown gas

Reference no: EM13213638

An effusion container is filled with 1 L of an unknown gas. It takes 40 s for the gas to effuse into a vacuum. From the same container under the same conditions--same temperature and initial pressure, it takes 40 s for 1.00 L of O2 gas to effuse. Calculate the molar mass (in grams/mol) of the unknown gas.
