Introduction for Module 9 – Gas Mixtures
Textbook: Open Stax Chemistry 2e
Suggested Reading: Chapter 9.3
Learning Objectives:
- Describe how gases combine in a mixture
- Calculate properties of gas mixtures using the relationship between partial and percent composition (mole fraction) of each species
- Define vapor pressure and its relationship to the partial pressure of water within a saturated gas sample
- Calculate how vapor pressure of water contributes to a mixture collected over water
Captions and Attributions:
- Subset of a vapor pressure table showing the dependance of the vapor pressure of water on temperature
- A schematic diagram illustrating different partial pressures of gases in a sample collected over water
