Agas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. it required 120 s for 1.0 l of the gas to effuse. under identical experimental conditions it required 32 s for 1.0 l of o2 gas to effuse. you may want to reference (pages 416 - 419) section 10.8 while completing this problem. part a calculate the molar mass of the unknown gas. (remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 l; that is, rate and time are inversely proportional.)
