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

PURPOSE : Â Â Â Â Â Â Â Â In this particular laboratory experiment, we ar dismission to restrain the molar mass of an unknown gas, from the gas density. We be also going to use gas density, along with the kinetic molecular theory, to explain the behavior of gas filled balloons. Finally, we be going to demonstrate the effects of temperature and pressure changes of gasses. PROCEDURE : Â Â Â Â Â Â Â Â We ar using the data-based procedure as described in our laboratory manual.

MATERIALS and APPARATUS : Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â office A-1: In this part of the experiment, we are going to observe lead balloons filled each with bingle of trine different gasses. So as part of our materials we departure to do three balloons as nearly as the three gasses. These balloons were already prepared for us and we kept underneath the pay back hood for observation.

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Laboratory Stock Â Â Â Â Â Â Â Â Part A-2-5c: Â Â Â Â Â Â Â Â During this part of the experiment, our materials and equipment consisted of one, clean, dry, 500mL plastic store with an airtight cover. Along with the bottle we need an electronic balance, a thermometer set up to assess the air temperature, 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.
