5.A gas of unknown molecular mass was allowed to effuse through a small opening under constant pressure conditions. It required 72.0 seconds for 1.00 L of the gas to effuse. Under identical experimental conditions it required 28.0 seconds for 1.00 L of oxygen gas to effuse. Calculate the molar mass of the unknown gas. Remember that the faster the rate of effusion, the shorter the time required for effusion, the rate is inversely proportional.
