Using Moles to Count Atoms

In this atoms, mass and the mole worksheet, learners 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.

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

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

In this molarity worksheet, students determine the concentration or molarity for each of the solutions. Students manipulate the molarity formula to calculate the moles, mass, or volume of each problem.

In this molecules, moles and molar masses worksheet, learners find the atomic masses of 8 elements, they write the formulas for 6 diagrams of molecules and they find the molecular masses of 12 compounds. Students also find the fraction...

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...

Only three slides comprise this collection. The first defines molecular weight and molar mass. The second lists the molar mass and number of particles in a mole of several substances. The third is a chart depicting a chemical reaction...

Relative molecular masses sure have a lot of decimal places! Watch the video to learn how the number of particles in one mole of carbon-12 determines relative atomic and molecular masses. Viewers also learn how to calculate the...

Consisting entirely of photos and simple graphics, this fundamental video is an informative presentation. Topics include elements, molecules, chemical bonds, atomic mass, isotopes, and ionization. Because it covers a wide range, it would...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...
