1. A student weighs an empty special round bottom flask and stopper. He finds the mass to be 56.972 g. He then adds about 5 mL of an unknown liquid and heats the flask in a boiling water bath at 100°C. He allows all the liquid to vaporized and then removes the flask from the bath, stoppers it, and lets it cool. Upon cooling, he briefly removes the stopper, then replaces it and weighs the flask and condensed vapor, obtaining a mass of 57.917 g. The volume of the flask is known to be 240.2 mL. The barometric pressure in the laboratory that day is 743 mm Hg. What was the pressure of the vapor in the flask in atm? O 0.9776 atm 0.98 atm 0.978 atm 0.977 atm
