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.)

Gases : GasGramMixPressure (5 Variations)
4.80 g of CH4 is mixed with 17.6 g of CO2 in a 9.00 L flask at a temperature of 67.2oC. What is the total pressure of the flask? (Assume there is no reaction.)
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.

Gas Clathrate Hydrates Experiment for High School Projects and Undergraduate LaboratoriesMelissa P. Prado, Annie Pham, Robert E. Ferazzi, Kimberly Edwards, and Kenneth C. Janda Presents a procedure for preparing and studying propane clathrate hydrate. This experiment introduces students to this unusual solid while stimulating a discussion of the interplay of intermolecular forces, thermodynamics, and solid structure. Prado, Melissa P.; Pham, Annie; Ferazzi, Robert E.; Edwards, Kimberly; Janda, Kenneth C. J. Chem. Educ.2007, 84, 1790.
