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...

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...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

In this chemistry exam worksheet, students solve fifteen problems related to acids and bases, rates of reactions, and half life.

How many calculations can you think of that include moles? Chances are, plenty! Show young chemists the uses of the multifaceted mole with thought-provoking puzzles. Individuals identify and associate the outcomes of molar quantities...

In this Avogadro's law worksheet, students read about gases and learn that under the same conditions of pressure and temperature gases with equal volumes have the same number of moles of particles. Students use Avogadro's law to solve 8...

In this chemistry worksheet, students locate and identify various vocabulary terms related to chemistry. There are nine words/phrases located in the puzzle to find.

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...

For this ideal gas law, molar mass and density worksheet, students read about how the molar mass and density of a gas can be determined from the ideal gas law. They solve five problems using the ideal gas law to find the pressure,...

In this chemistry worksheet, students identify and write how many significant figures they would use for each problem. Then they round the answers to the appropriate number of significant figures. Finally, students calculate the mass of...

In this gas stoichiometry worksheet, learners use the ideal gas law and balanced chemical equations to solve for unknown values such as volume and mass of gases.

In this stoichiometry worksheet, learners identify types of reactions, show the products, and balance the equations. Students determine the limiting reagent, theoretical yield, and percent yield for given reactions. This worksheet has 5...

Video describes how moles are used in chemistry and how their size is measured. [4:33] Followed by a short quiz and a list of additional resources to explore.

This site deals with Amedeo Avogadro, his life, his contributions to chemistry, and his famous number.

This slide and audio book shows how to relate mass to a number of particles by using many formulas, examples, and real life scenarios. View the weighted average calculations, Avogadro's number, the atomic mass of carbon, and molar mass.

[Free Registration/Login Required] In the mole carnival, students count the number of atoms and particles in different objects found at the carnival. As students work to find the number of particles, they practice counting particles by...

A collection of video lectures to teach junior high students topics in chemistry. Lectures cover topics in understanding the periodic table, compounds, chemical bonding, Avogadro's number, balancing chemical equations, stoichiometry,...

Animation depicting Avogadro's Law or how the volume of a gas is affected by the number of gas particles. See what happens to the volume of a gas when the pressure and temperature stay constant.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will identify three methods for measuring the amount of matter in a sample. They will define the mole and its relationship...

Through informational text, interactive practice problems, virtual simulations, and video clips, students learn about the gas laws.

This page from Iowa State University describes the various experimental ways that Avogadro's number has been determined.

A page, written by Donald E. Simanek of Lock Haven University discusses misused and misunderstood physics terms and concepts. It reminds us that Avogadro's number is a constant, and should be treated as such.

An introduction to the mole, a unit of measurement that quantifies atoms and molecules.

Watch a short tutorial showing the conversion between the amount of a substance expressed in number of molecules to the amount of a substance expressed in moles of molecules, and then try some dimensional analysis practice problems.
