Introduction This experiment can be broken up into two parts. During the first portion, we will determine the molecular mass of an unknown gas using the ideal gas law. The molar mass will not be exactly what the understood value is, however, we will then use it along with the density, temperature, and pressure to solve for R, the gas constant. Procedure The first step is to heat up 1 liter of water on a hot plate. Construct the necessary Erlenmeyer flask by capping the top with aluminum and tying it off with copper wire. Place between 3 and 4 milliliters of the unknown into the flask. Mass the flask. Then suspend the flask in the hot water until the unknown is entirely vaporized. After vapors appear to stop escaping from the top of the flask, it is safe to assume it has all been vaporized. Set the flask aside and allow it to cool. The unknown with condense into a liquid inside the flask. Wipe and dry the flask removing all excess water on the outside. Weigh the flask again. Repeat the experiment twice more. To
