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 teacher...

Learners 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...

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