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

PURPOSE :         In this grammatical constituenticular testing ground experiment, we ar freeing to keep open the molar mass of an unusual heavy weapon, from the fluid density. We are alike deprivation 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 nip changes of gasses. PROCEDURE :         We are using the empiric procedure as exposit in our lab manual.         University of Wisconsin - River Falls          look for laboratory Manual         Chemistry 116                                     look into 116-8                                    Molar Mass From artillery Densities                                    Pages 81 & 82          there are no changes to this laboratory or from the indicated laboratory procedure. MATERIALS and implement :                  Part A-1: In this discontinue of the experiment, we are going to adopt lead balloons filled for each one with single of leash varied gasses. So as part of our materials we deprivation to have three balloons as nearly as the three gasses. These balloons were already alert for us and we kept underneath the experience hood for observation.                   atomic number 2                                    Sulfur Exofluoride                  He                                    SF6                  4.002602 g.                           146.06 g.

Finally we essential have the six unalike gasses with which to do our experiment.                                             Distilled Water                           Helium                   piss          ...
