Detailed discussion of stoichiometry, mols, and percents. Includes examples showing dimensional analysis (factor-lable method) and a link to the mole road map (a diagram which leads one through the stoichiometric problem-solving process).

Using the example of a cake recipe, young scholars find the ratios between different ingredients, which introduces the concept of mole ratios. They then calculate the mole ratios in a chemical equation, and learn how this applies to...

See examples of the three types of gas stoichiometry problems: mole-volume, mass-volume, and volume-volume.

In this activity, students use the virtual lab to create a 0.025M glucose solution from a standard 1M glucose solution. First, they calculate the correct volumes of 1M glucose solution and water to mix together to create the final 0.025M...

In this activity, students use the virtual lab to create dilute solutions from a concentrated stock solution of acids or bases. They must first calculate the correct volumes of concentrated acid solution and water to mix together to...

In this activity, students use the virtual lab to create 500mL of 3M HCl solution from a concentrated stock solution of 11.6M HCl. They must first calculate the correct volumes of 11.6M HCl solution and water to mix together to create...

Explains the essence of limiting reactant problems using a sample problem: How can an amount of product (KNO3) be predicted from amounts for two reactants (KCl and HNO3)? Shows the work and explains how to solve these types of problems.

[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...

A lengthy page covering most all the gas laws. Each law is described in words and stated as an equation. The use of each law in solving problems is demonstrated. Some problem-solving tips are provided. There are 23 practice problems with...

This digital textbook covers core chemistry concepts and includes interactive features, real-world examples, and videos.

Middle of a slide show on stoichiometry that shows a nice graphical look and example of limiting reagents.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will learn to calculate the amount in moles of a reactant or product from the mass of another reactant or product. They...

A collection of video lectures to teach junior high students topics in chemistry. Lectures cover topics in understanding the periodic table, compounds, chemical bonding, Avogadro's number, balancing chemical equations, stoichiometry,...

A collection of video lectures from a general chemistry course taught at the University of California, Berkeley. The course teaches periodic table, chemical bonds, molecular shape, phase changes, chemical reactions, stoichiometry,...
