Discussion/Conclusion: The ideal gas law ad the behavior of gasses were studied in this experiment by measuring data from simple experiments and examining how well they fit the theoretical data. For the first part of the experiment an unknown liquid was placed in a hot water bath and allowed to evaporate. The weight of the remaining gas was calculated by subtracting the previously measured weight of the empty flask from the new weight of the flask with the vapor. Using the weight of the gas and the moles of it, calculated using the ideal gas law, the molar mass was calculated and using a chart of molar masses, the unknown was identified. The procedure asks for the flask to be completely dry before adding the unknown liquid because the results would be set off by even a small amount of water left from rinsing. If a drop of water was left, when vaporized at 100 C and 1atm, there would be .0016 moles of water in the flask. The moles of the water would take up .0294 mL of the flask, which is of considerable size when looked at with respect to the size of the flask. For the experiment, the weight of the Erlenmeyer flask with water was measured even though the volume was stated on the flask itself to set a standard and reduce error in the measuring resulting form the individual variations of each scale.
