## Unit 9 Reaction Stoichiometry- Using the Mole with Chemical Equations

**Resources**

**Learning Objectives**

1. Calculate the mass of one mole of any substance (the molar mass)

2. Use molar mass in calculations- example: given moles, find mass.

3. Identify and use the mole ratio from a balanced equation in reaction stoichiometry problems.

4. Solve basic reaction stoichiometry problems. Mole-mole, Mass-mass, Mass-molecules.

5. Understand how to use molar volume to convert between moles and volume of a gas at STP.

6. Solve basic reaction stoichiometry problems involving the volume of a gas at STP.

7. Distinguish between limiting and excess reagent.

8. Define and determine percent yield.

9. Solve a limiting reagent problem.
