Review Sheet for Gas laws Name ___________________________ 1. A gas at 2.3 atm occupies 12 liters. The volume is changed to 6 liters what is the resulting pressure? 2. A sample of gas is confined to 30ml at a pressure of 6 atmospheres. When the pressure is changed to 3liters‚ what is the resulting pressure? 3. A gas occupies 30 L. When the gas is heated from 50C to 100C‚ what is the final volume? 4. In a lab‚ Neon vapor occupied a volume of 1 liter at STP‚ the volume was changed to 4 liter

Determination of the Molar Mass of Volatile Liquids Theory: Molar masses‚ can be seen and used daily in chemistry. In this lab‚ the ideal gas law helps determine and evaluate the molar mass of gases and volatile liquids. The ideal gas law compares four properties of a gas which include pressure‚ volume‚ moles‚ and temperature. During this experiment‚ the moles would be unknown‚ in effect the student must use a substance mass divided by its molar mass. With this‚ the ideal gas law can be arranged

A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operating limits‚ spillage of the beads‚ risk of head injury from bending over to change the beads in the apparatus or from the low bar‚ and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic
