Gases : IdealGasMolarMass (10 Variations)
A sealed flask contains 3.1 L of a gas at 2.4 atm and 22.7oC. If the density of the gas is 9.7 g/L, what is its molar mass? (You can assume that the gas behaves ideally.)
Using Graphs of Gibbs Energy versus Temperature in General Chemistry Discussions of Phase Changes and Colligative PropertiesRobert M. Hanson, Patrick Riley, Jeff Schwinefus, and Paul J. Fischer The use of qualitative graphs of Gibbs energy versus temperature is described in the context of chemical demonstrations involving phase changes and colligative properties at the general chemistry level. Hanson, Robert M.; Riley, Patrick; Schwinefus, Jeff; Fischer, Paul J. J. Chem. Educ.2008, 85, 1142.

Does the Addition of Inert Gases at Constant Volume and Temperature Affect Chemical Equilibrium?João C. M. Paiva, Jorge Gonçalves, and Susana Fonseca This article examines three approaches, leading to different conclusions, for answering the question "Does the addition of inert gases at constant volume and temperature modify the state of equilibrium?" Paiva, João C. M.; Gonçalves, Jorge; Fonseca, Susana. J. Chem. Educ.2008, 85, 1133.
John Krenos Metiu has created a significant set of volumes on undergraduate physical chemistry. The integration of Mathematica and Mathcad workbooks into the four texts provides instructors with an attractive new option in teaching. Krenos, John. J. Chem. Educ.2008, 85, 206.
