### Stoichiometry and Gravimetric Stoiochiometry Lesson Plan

#### Content

Moles, Mole Ratios, Limiting Reactant, Excess Reactant, Theoretical Yield,
Actual Yield, Percent Yield

#### Goals / Aims of The Lesson Plan

1. Explain the sequence of steps used in solving stoichiometric problems

2. Use the steps to solve stoichiometric problems

3. Calculating the corresponding mass, or quantity in moles or molecules,
for any given reactant or product in a balanced chemical equation.

#### Objectives

1. Identify quantitative relationships in a balanced equation

2. Determine mole ratios from balanced equations

3. Identify limiting reactants in a chemical equation

4. Identify excess reactants in chemical equations

5. Determine the percent yield for a chemical reaction

6. Students will learn the process to solve gravimetric stoichiometry problems.
