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...
