The Mole

In this atoms, mass and the mole worksheet, students are given 18 problems to solve for the number of atoms, the mass of the substance or the moles of the substance. Students show their work and include all the units of measurements.

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

In this moles worksheet, students define a mole and convert grams to moles or moles to molecules. Students convert specific mass of compounds to moles. This worksheet has 1 true or false, 6 short answer, 3 fill in the blank, and 15...

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...

You didn't know you'd find moles in chemistry class! Through the introduction of moles and molar volume at STP, classes see how to calculate moles using a given chemical equation. The presentation includes a short review of ions in...

Pretend to be an Epidemic Intelligence Service officer for the Centers for Disease Control and Prevention. Detectives deal with data and make decisions to determine the dawn of the disease!

In chemistry, the mole is a unit of measurement, much like a millimeter or liter. After learning about moles, scholars learn various equations relating to mass, volume, and concentration. They review each of these equations in a few...

Take the difficulty out of classifying matter with an easy-to-follow activity that makes distinguishing between pure substances and mixtures simple. Scholars explore how matter is grouped between two categories—pure substances and...

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...
