stoichiometric (molarity, gases, mass)

Nine questions about gases allow your advanced chemistry class to apply what they have learned about the behavior of gases. Problems are solved using all of the gas laws. The format is tidy and allows plenty of space for problem solving....

This problem-solving worksheet deals with properties of gases. Junior chemists apply the Ideal Gas Law to a variety of gases in order to calculate density or molar mass. It is straightforward and would be best used as a homework or...

Using Graham's Law, your young chemists will calculate effusion rates for gases or masses involved. There are only three problems to solve on this learning exercise, making it a convenient time-filler for those who work quickly, or an...

The topic of moles, reaction volumes, and masses is tested here. There are ten questions with situations that need values related to PVT and density calculated.

A number of word problems are given here and your class will have to calculate and setup them up, using units and full formulas.  The questions following each problem ask about molarity and volume.

Young scientists consider the volumes of gases, liquids or solids under varying conditions. This complicated sheet assumes detailed prior knowledge and has no details apart from the chemical names in the real-life situations presented....

This study guide will help your young chemists hone their skills with several gas laws. It acts as a comprehensive review of the behavior of gases and can be used as preparation for a quiz, or as the quiz itself. Keep this convenient...

Four practical example problems are given on this instructional activity. Young chemists solve for the volume or molar mass of different gases under given conditions. This resource would be effective as a class warm-up, pop-quiz, or...

Sal continues his explanation of The Ideal Gas Equation in this chemistry video. He sets up a different problem from the previous video, and uses the ideal gas equation to calculate the molar mass of a 98 ml container that contains .081...

What's in your teacher toolbox for gas laws instruction? Make some room for a creative alternative! Young chemists discover how molar volume relates to mass and moles using logic puzzles. With helium as the model gas for the lesson, your...
