A sample of N2 gas is contaminated with a gas (A) of unknown molar mass. The partial pressure of each gas is known to be 200. torr at 25°C. The gases are allowed to effuse through a pinhole, and it is found that gas A escapes at 2 times the rate of N2. The molar mass of gas A is: 56 g/mol 14.01 g/mol 7.00 g/mol 112 g/mol none of these

A student devised an experiment to determine the molar mass of an unknown gas X. Firstly, he filled a glass gas syringe (accurate to ± 0.5 cm3 ) with 100 cm3 of air then placed a rubber seal over the nozzle and weighed the syringe. He then emptied the gas syringe, refilled it with 100 cm3 of the unknown gas X, replaced the rubber seal and reweighed the syringe. Finally, he measured the temperature of the room. He obtained the...
