In this percentage worksheet, students calculate percentages given various types of problems. They calculate percent of compounds in a solution, they calculate mass of compounds given percentages of solutions, and they percentages of...

In this molecular mass and percent composition learning exercise, high schoolers find the molecular mass of 10 compounds to three decimal places. They also find the percent composition of 7 compounds and express their answers to two...

Wow! This is one of the most exhaustive presentations on finding chemical formulas that you will come across! Beginning with the basics, and leaving junior chemists with procedures and concrete examples, this PowerPoint certainly...

Everyone knows water is made of hydrogen and oxygen ... but how much of each? Science scholars explore percent composition through a video from JFR Science. The narrator provides background information, time-saving tips, and example...

99 percent of the species that have ever lived on this planet are extinct. The best way to understand when another extinction could happen is to study the previous five mass extinctions. The video discusses each one, the cause, the...

Do you need a fast and thorough way to instruct your class members on how to determine the percent composition of a compound? Then this short resource will be a wonderful addition to your existing instructional methods. The video...

High schoolers find the percent composition of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a sample of potassium chlorate to decompose it into potassium chloride and oxygen. They weight their...

More than half of your body is made of water, but what percentage of you is made up of hydrogen? This video explains how to solve for percentage mass. It uses water as one example of solving for both hydrogen and oxygen.
