- Exp 13B Stoichiometry and Molar Volume of hydrogen gas
- Diffusion of gases
- Temperature related to Kinetic Energy
- KE = 1/2 (mass ) (velocity)2
- The less massive the particle the faster it diffuses at same temp and pressure.
- Graham's Law of Diffusion
- Demonstration: molecule races: HCl vs. NH3
- 3 problems
- calculate relative rates of velocity
- calculate molar mass of unknown gas given relative rates of velocity
