JUNIOR CHEMISTRY
The Mole 1 - introduces the mole concept; Avogadro's number
The Mole 2 - converts atoms to moles; performs molar mass calculation
The Mole 3 - converts mass to moles; mass to atoms
Stoichiometry 1 - gives the answer to: How many moles of silver chloride forms when 2.6 mol of KCl reacts with excess
silver nitrate in solution.
Stoichiometry 2 - takes you through a stoichiometry problem that involves finding a mass of product where a reactant
mass is known
Stoichiometry 3 - performs a limiting reagent question
AP CHEMISTRY
Stoichiometry 1 - teaches the atomic weight (molar mass) calculation and mass percent
Stoichiometry 2 - does a question that converts % composition by mass into an empirical formula
Stoichiometry 3 - calculates the water of hydration (crystallization) of an ionic compound
Georgia Public Broadcasting Video Lectures
This public station has an entire high school level chemistry course online. This is not an honors-level course
like ours but the videos are useful nonetheless. Each video is a 30 minute lecture on a very specific topic.
If you want to try their note-taking system for the lecture, print out the “Note Taking Guide” on the page.

Chapter 3: Chemical Reactions and Earth's Composition
There is a diagnostic quiz (some of the questions cover topics that not relevant for us). The ChemTours (basically
multi-media tutorials) are excellent and I highly recommend them. You should look at the ones on:
Avogadro’s Number Percent Composition Limiting Reactant
Education Portal – Chemistry 101: General Chemistry
Avogadro's Number: Using the Mole to Count Atoms
Mole-to-Mole Ratios and Calculations of a Chemical Equation
Mass-to-Mass Stoichiometric Calculations
Stoichiometry: Calculating Relative Quantities in a Gas or Solution
Limiting Reactants & Calculating Excess Reactants
Calculating Reaction Yield and Percentage Yield from a Limiting Reactant
Calculating Percent Composition and Determining Empirical Formulas
Hydrates: Determining the Chemical Formula From Empirical Data
