Unit 6: Mole & Stoichiometry

Learning Objective for Unit 6 is located here.

Atoms and molecules are so small, but chemists use a method of counting by weighing to measurement amounts. This is very useful as we see the information contained in a balanced chemical equation. This will lead us into stoichiometry: a concept that looks funny and might be scary to learn, but once you've got it you have just accomplished a major part of chemistry. To be discussed: molar ratios, mole:mole stoichiometry, limiting and excess reactants, and percent yield.
