A gas of unknown molecular mass was allowed to effusethrough a small opening under constant-pressure conditions.It required 105 s for 1.0 L of the gas to effuse. Underidentical experimental conditions it required 31 s for 1.0 Lof O2 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 of 1.0 L; inother words, rate is the amount that diffuses over the timeit takes to diffuse.)
Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced. Suppose the CO₂ gas evolved by a certain chemical reaction taking place at 50.0 °C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 55.7 mL. g x10 057 Sketch of a gas-collection apparatus x collected gas Calculate the mass of CO₂ that is in the collection tube.
