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

PURPOSE :         In this dissolveicular enquiry laboratory experiment, we ar freeing to sustain the molar mass of an strange triggerman, from the catalyst density. We are as well as passage to use gas density, along with the kinetic molecular(a) theory, to explain the behavior of gas filled balloons. Finally, we are going to demonstrate the effects of temperature and drag changes of gasses. PROCEDURE :         We are using the experimental procedure as depict in our laboratory manual.         University of Wisconsin - River Falls         research laboratory Manual         Chemistry 116                                     audition 116-8                                    Molar Mass From throttle valve Densities                                    Pages 81 & 82         thither are no changes to this laboratory or from the indicated laboratory procedure. MATERIALS and utensil :                  Part A-1: In this split of the experiment, we are going to view lead balloons filled each with single of trio divers(prenominal) gasses. So as part of our materials we deprivation to have three balloons as nearly as the three gasses. These balloons were already wide-awake for us and we kept underneath the experience hood for observation.                  helium                                    Sulfur Exofluoride                  He                                    SF6                  4.002602 g.                           146.06 g.

Finally we must have the six assorted gasses with which to do our experiment.                                             Distilled Water                           Helium                  water system          ...
