[Free Registration/Login may be required to access all resource tools.] Students will calculate the concentration of solutions in units of molarity, and use molarity to calculate the dilutions of solutions.

As part of the "Basic Atomics" section of the Virtual Textbook, this site examines moles. The information presented defines moles in relation to Avogadro's number and then goes on to describe molar mass and molar volume.

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals...

An animation to investigate the rates of heating or cooling in a calorimeter. Also, molar enthalpy of solution of sulfuric acid is discovered.

[Free Registration/Login may be required to access all resource tools.] Based on the balanced chemical equation, students will calculate the masses or moles of reactants or products generated in a given reaction. They will also convert...

An interactive simulation that teaches about Beer's Law, solutions, concentration, spectrophotometry, and more through observations to explore how much light is absorbed and transmitted with changes in thickness and color. This...

[Free Registration/Login may be required to access all resource tools.] Students write the solubility product constant expressions for nearly insoluble ionic compounds and perform calculations for compounds and solubility.

This site deals with Amedeo Avogadro, his life, his contributions to chemistry, and his famous number.

Learn about the life and work of Amedeo Avogadro, who was most noted for his contribution to molecular theory now known as Avogadro's law.

This chemistry tutorial helps students understand that formula mass is the total of all the atomic masses of a chemical formula.

Students have the opportunity to study examples and worked out example problems to further their understanding of chemical solution concentration.

Explanation of how to calculate empirical and molecular formulas.

Heat is defined and explained; the concept of heat is related to the kinetic motion of particles and to temperature. Heat capacity and specific heat are explained. Sensible heat is compared to latent heat; reference is made to the heat...

This section from the online textbook, "An Introduction to Chemistry", gives the steps to calculate the percent of an element in a compound. A few example calculations are shown. Also find links to chapter maps and power points for other...

Explains vocabulary used when talking about the yield of a chemical reaction and models how to calculate the theoretical and the percentage yield in an example problem.
