Converting Amount to Mass

Colored boxes with white font present the basic periodic table of elements to your young chemists. All of the basics are included: chemical name, symbol, atomic number, atomic mass, and the number of electrons in each orbital. A brief...

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...

After giving the definitions of the different compound terms and formulas, equations are provided to teach your chemists to calculate different values. Relative formula mass, atomic mass, and empirical mass are shown and explained with...

Two animated slides explain the decomposition reactions that occurs within a catalytic converter. An enthalpy diagram is displayed. Hess's Law is demonstrated. Finally, the analogy of football is used to explain Hess's Law. This...

Students of chemistry are shown how to calculate the empirical formula from a molecule's mass composition. Sal uses a variety of elements from the Periodic Table to demonstrate the process and the calculations involved to arrive at the...

Sal builds on the previous video which shows students how to calculate the mass composition of a compound from its empirical formula. This problem uses the elements Hydrogen, Oxygen, and Sulfur. The process requires quite a bit of...

Students find the standard molar volume of a gas. In this molar volume of a gas lesson plan, students react magnesium metal and hydrochloric acid and collect the hydrogen gas produced using a gas collection tube. Students calculate the...

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. 

Young scholars find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

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...
