A whirlwind tour through the world of stoichiometry, including basic stoichiometric ideas, simple calculations, mole ratios, limiting reagent, percent yield, and experimental error. Using humor and plenty of examples, your students should become stoichiometry pros in no time. Note: I do not include stoichiometric calculations involving quantities of atoms or molecules. Though I know this is sometimes taught, I have never once had anybody ask me to tell them how many molecules are going to be
