General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

Young scholars research chemical formulas and balance chemical equations.  In this chemical equations lesson students complete a class activity on chemical equations and answer questions.

Students perform a series of experiments on gas laws. In this chemistry lesson, students analyze the relationship between temperature, volume and pressure. They create a poster summarizing all the gas laws.

In this chemistry worksheet, learners memorize a pneumonic phrase in order to remember the Gas Law and then apply this to other content as well.

Students explore the concent of using the mole to solve problems related to counts small particles of matter. Students work individually and in groups to complete conversions of substances from moles to matter.

Students recognize methods used to define the mole. After converting various quantities to the mole, students provide a context for understanding the usefulness of scientific notation and the mole.
