You are going to find the molar mass of an unknown compound. The experiment involves putting the compound in an Erlenmeyer flask and covering the top with aluminum foil with a small hole in it, then heating the compound until all the liquid is in the gas phase. The temperature in the hot water bath and the pressure in the room are recorded, and then the unknown gas is allowed to cool and condense to a liquid. Then it is weighed. Last the volume that the gas occupied in the Erlenmeyer flask is determined by filling the flask with water and measuring the volume of water with a graduated cylinder. The values of the volume, pressure, temperature, and mass of the unknown are given for you in the excel file for problem set #5. Determine the Molar Mass of your unknown compound. Show all work. Also give all your starting values below. Volume_155 ml pressure 685.5 mmHg ,temperature_98.6 C_ and mass_0.609 g.
