Stoichiometry
Stoichiometry is the accounting or bookkeeping of chemistry. Using equations like recipes can help us make predictions about how much product is produced or how much reactant is needed. We will look at the balanced equation to give us mole ratios to determine the following relationships: Mass/Mole, Mole/volume, mole/mole, mole/atoms calculations. Percent Yield, Percent Error, Limiting Reactants calculations.
Key Vocabulary

Generalizations: The student understands that . . .
Balanced equations show molar relationships.
