1. You are given a quantity of a volatile liquid substance and asked to determine its molecular weight. To do that, you place a sample of the liquid in a 200.0-mL flask and submerge the flask in a boiling water to vaporize all of the liquid. The vapor fills the flask and the excess escapes,. Now you cool the flask so that all the vapor in it condenses, and you weigh the flask and liquid. After you subtract the mass...
