4.49

4.51

4.63

4.85

4.101

Potential topics for the quiz questions include:

- application of the ideal gas law to calculate P, V, n, T, density, molar mass (4.19; 4.33; 4.37; 4.41; 4.87; 4.101)

- stoichiometric calculations for reactions that include gaseous reactants and/or products (4.49; 4.51; 4.85; 4.101)

- calculation of partial pressures (4.51; 4.85)

- molecular motion: effusion rates to calculate molar masses (4.63; 4.87)

There will be two or three quiz questions similar to the problems given above. I recommend you prepare for quizzes by working all these problems ahead of time. See me in office hours (M 2-3pm, T 9-10am and W 10-11am and 2-3pm) if you have questions.
