A student weights an empty flast and stopper and finds the mass 2 be 54.868g. She then adds about 5mL of an unkown liquid and heats the flask in a boiling water bath at 100 degrees C. After all the liqiud is vaporized, she then removes the falst from the bath, and lets it cool . After it is cool she momentarily removes the stopper, then replaces it and weighs the falsk and condesned vapor, obtaining a mass of 55.802g. The volume is known to be 242.mL. The baramoetic pressure in the lab that day is 747mm Hg.
What is the pressure of the vapor in the flask in atm?
What was the mass of vapor that was present in the flask?
