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 : GasMoleMixPressure (5 Variations)
What is the pressure exerted by a mixture of gases in a 40.0 L container at 127oC if the mixture contains 0.100 mol O2, 0.400 mol CH4, and 0.500 mol SO2?
Similarity and Difference in the Behavior of Gases: An Interactive DemonstrationGuy Ashkenazi A demonstration that concurrently exposes differences and similarities in the behavior of two different gases has been designed to bridge the gap between students' understanding at the algorithmicmacroscopic and conceptualmicroscopic levels.

Concept Maps for General Chemistry Boyd L. Earl Two concept maps have been developed to represent the organization of the material in a first-semester general chemistry course. By providing these maps to students and referring to them in class, it is hoped that the instructor can assist students in maintaining a grasp of the "big picture" during the progress of the course. Earl, Boyd L. J. Chem. Educ.2007, 84, 1788.
