4. Warm - Up
Carbon dioxide gas occupies a volume of 200 ml at STP. What is the density of the gas?
How do I know when to use the combined gas law, ideal gas law and graham’s law to solve problems?

5. Objectives Today I will be able to:
Apply Boyle, Charles, Gay-Lussac, Combined, Ideal and Dalton’s gas law to solving problems

6. Homework
Finish practice problems

7. Agenda Warm Up Dalton’s Law Notes Dalton’s Law Practice

8. Dalton’s Law

9. Dalton’s Law of Partial Pressures
The sum of the pressures of all gases present in a system equals the total pressure of the system
P1 + P2 + P3 + … = Pt

10. Dalton’s Law Practice
Complete the practice at your desk. If you have questions, please ask Ms. Ose. We will review selected problems

11. Mixed Gas Law Problems
Complete the practice problems at your desk. If you have questions, ask Ms. Ose for help.
