Dalton's Law of Partial Pressures
Students will calculate partial pressures of gases in a mixture and understand their relationship to total pressure.
Key Questions
- Explain the relationship between the partial pressure of a gas and its mole fraction in a mixture.
- Predict the total pressure of a gas mixture given the partial pressures of its components.
- Analyze how Dalton's Law is applied in collecting gases over water.
