Evaluate the molar mass of the unknown gas

Reference no: EM13322459

A gas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. It required 125 for 1.0 of the gas to effuse. Under identical experimental conditions it required 28 for 1.0 of gas to effuse. Calculate the molar mass of the unknown gas.
