Chapter 10: Additional Diffusion Problems
Date _____/_____/_____ Period _____
1. What is the ratio of speed of hydrogen molecules to the speed of neon atoms when the
gases are at the same temperature and pressure?
2. At a certain temperature, the velocity of chlorine molecules is 0.0410 m/s. What is the
velocity of sulfur dioxide molecules at the same temperature and pressure?
3. What is the ratio of the speed of carbon monoxide molecules to that of nitrogen monoxide
molecules when both gases are at the same temperature?
4. The rate of effusion of an unknown gas was determined to be 2.92 times faster than that of
ammonia. What is the approximate molecular weight of the unknown gas?
5. Find the molar mass of a gas that diffuses 0.906 times as quickly as argon gas.
6. Unsure as to whether they have synthesized nitrogen monoxide or nitrogen dioxide,
Mr. Anastasio and Mr. Palmer measure their gas' rate of diffusion. They determine that
helium travels 2.74 times faster than their unknown gas. Identify their gas.
