Lab Report: determine the molar mass of an unknown gas, from the gas density

PURPOSE :         In this particular laboratory experiment, we ar handout to restrain the molar mass of an unknown gas, from the gas density. We argon also going to use gas density, along with the energizing molecular theory, to explain the behavior of gas filled balloons. Finally, we atomic number 18 going to demonstrate the effects of temperature and pressure changes of gasses. PROCEDURE :         We are using the data-based procedure as described in our laboratory manual.         University of Wisconsin - River Falls         research laboratory Manual          chemistry 116                                    Experiment 116-8                                    Molar Mass From Gas Densities                                    Pages 81 & axerophthol ; 82         There are no changes to this laboratory or from the indicated laboratory procedure. MATERIALS and APPARATUS :                   assort A-1: In this part of the experiment, we are going to observe lead balloons filled each with angiotensin-converting enzyme of common chord different gasses. So as part of our materials we loss to guard three balloons as nearly as the three gasses. These balloons were already prepared for us and we kept underneath the examine hood for observation.                  Helium                                    Sulfur Exofluoride                  He                                    SF6                  4.002602 g.                           146.06 g.

Along with the bottle we need an electronic balance, a thermometer set up to assess the air tempe rature, as well as a barometer with a chart on how to determine the readings. Finally we must have the six different gasses with which to do our experiment.                                             Distilled Water                           Helium                   piss          ...
