#2 3 of 10 2. (5 marks) A 5.76 g sample of helium (He, M = 4.00 g mol-1) is bubbled through liquid ethanol (C2H5OH, M 21.8 g mol-?) at 49.5°C. The gas is then collected and occupies a volume of 54.91 Lat 738 Torr. Assuming helium becomes saturated with ethanol vapour, calculate the vapour pressure (in Torr) of ethanol at 49.5 Tom Flom XLHA Tobou wolod rovin osat ord monoclona borbe prona seno to 20
