stoichiometric (molarity, gases, mass)

Start stoichiometry scholars off on the path to success with a short video. The narrator of this interesting video guides viewers through the concepts of the mole, molar mass, and Avogadro's number. Additional topics include converting...

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...

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....

Four practical example problems are given on this worksheet. 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 short homework...

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.

What is the density of octane gas and what is the molar mass of an unknown gas? These are the questions chemistry learners are asked to answer on this abbreviated assignment. Write these problems on the board for eager learners to...

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....
