1. A volatile organic liquid with known molecular weight is added to a vapor density flask which has a known volume. The flask is heated using a boiling water bath until all of the liquid has evaporated. After heating for an additional 1 or 2 minutes, the flask is removed from the boiling water bath, corked, and cooled using a room temperature water bath. Predict the mass of condensed vapor. Temperature of the hot water bath (ºC): 99.5 Volume of...
