Avogadro's Number Teacher Resources

Who was Lorenzo Romano Amedeo Carlo Avogadro? He was the guy who suggested that equal volumes of gases at the same temperature and pressure should contain equal numbers of molecules. This eventually led to a new quantity for the number...

Sal introduces chemistry students to the concept of "moles." He points out that a mole is number that helps a student to translate between grams and atomic mass units of any substance. Sal uses the element Aluminum to illustrate this...

Avogadro did not find or create Avogadro's number—it was just named after him out of respect for his work. The Socratica chemistry playlist presents a must-see video introduction to the mole. It details how to convert to moles from mass,...

The need for a counting unit is mentioned as you introduce the mole to your young chemists. Use this presentation to explain Avogadro's number and describe the incredible quantity it represents. Lecture notes are included for most of the...

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...

Students investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio of...

Students design an experiment to determine Avogadro's number. Students utilize an ammeter, an electrolytic cell and internet research.

In this chemistry review worksheet, students practice using Avogadro's number, calculating number of moles, and using the gas laws. This worksheet has 39 multiple choice questions.

What can you call a tooth in a glass of water? A one-molar solution! Presentation covers moles, Avogadro's Number, calculating formula mass, converting moles to grams, converting grams to moles, and calculations with moles. It is...

Avagodro's number (The Mole) ... you are not researching that cute little mole on your cheek! Avagodro's number refers to The Mole, a vital component to chemistry. This video segment will discuss the mole and further elaborate on...

Using chalkboard animation, this video thoroughly explains the three empirical gas laws: Avogadro's, Boyle's, and Charles'. Use it as an introduction when teaching young chemists about the properties and behavior of gases.

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...

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...

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...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

In this atomic theory worksheet, students use Planck's constant, Rydberg constant, and Avogadro's number to complete 20 multiple choice questions.

There's a mole in your classroom! Learners explore the meaning of a mole as a number through a video description. The instructor provides examples of elements, molecules, and formula units.

Learning about the mole using rice is pretty nice! Help your chemistry scholars visualize the concept of a mole of substance with an easy-to-perform lab. Partnered pupils find the mass of a single grain of rice and relate this...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

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,...

The definition of a kilogram is debatable. An informative video (as part of a larger playlist) shares the problem with the current definition of a kilogram. It explains why the concept became a challenge to explain as well as multiple...
