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 moles worksheet students complete a set of calculations to find how many atoms and moles are in different substances. 

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 ESL instructional activity, students describe 16 numbers to their partner, some in scientific notation. Students listen to their partner's numbers and write them down.

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...

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...

In this moles activity, students read about mole and learn how to calculate the number of moles in specific mass of compounds. This activity has 14 problems to solve.

In this ideal gas worksheet, students review Boyle's law, Charles's law, and Avogadro's principle. Students use this information to complete 3 problems.

In this ideal gas law, molar mass and density worksheet, high schoolers 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 activity, 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 chemistry worksheet, students locate and identify various vocabulary terms related to chemistry. There are nine words/phrases located in the puzzle to find.

In this gas laws worksheet, learners learn about the Universal Gas Equation. Students then use the equation to solve 6 word problems.

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

In this periodic table worksheet, students review atomic mass, molar mass, and percent composition of compounds. Then students complete 4 problems.

In this gas law worksheet, students review the Idea Gas Law equation and practice applying the equation to chemical reactions. Students write the balanced reaction, determine the limiting reagent, moles produced, and volume of gas...

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

In this waves worksheet, students use various formulas to calculate the wavelength, energy and frequency of waves. This worksheet has 5 word problems.

In this stoichiometry instructional activity, students 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...

An explanation the mole (named for molecule) and Avogadro's Number. One mole of a substance is equal to 6.022 times 10 to 23rd power units of that substance (such as atoms, molecules, or ions). The number 6.022 time 10 to 23rd power is...

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.
