**9.1 Introduction to Stoichiometry**

1. Define Stoichiometry. 2. Describe the importance of the mole ratio in stoichiometric calculations. 3. Write a mole ratio relating two substances in a chemical equation. 4. Calculate the amount in moles of a reactant or product from the amount in moles of a different reactant or product.

4
**Obj 1: What is Stoichiometry?**

Stoichiometry means Stoicheio = element Metron = measure Stoichiometry is the quantitative study of chemical reactions using balanced equations.

5
Obj 2: Mole Ratio Mole Ratios come from the coefficients in a balanced equation. Mole Ratios are used to convert moles of one substance (X) into moles of another substance (Y).

**Obj 4: Using a Mole Ratio 1 N2 + 3 H2 2 NH3**

7.5 mol N ? mol H ? mol NH3

10
**Obj 4: Using a Mole Ratio 1 N2 + 3 H2 2 NH3**

7.5 mol N ? mol H ? mol NH3 7.5 mol N2 (3 mol H2 ) = ? (1 mol N2 )

11
**Obj 4: Using a Mole Ratio 1 N2 + 3 H2 2 NH3**

7.5 mol N ? mol H ? mol NH3 7.5 mol N2 (3 mol H2 ) = 22.5 mol H2 (1 mol N2 )

12
**Using a Mole Ratio 1 N2 + 3 H2 2 NH3**

7.5 mol N mol H ? mol NH3 7.5 mol N2 (2 mol NH3) = ? (1 mol N2 )

13
**Obj 4: Using a Mole Ratio 1 N2 + 3 H2 2 NH3**

7.5 mol N mol H ? mol NH3 7.5 mol N2 (2 mol NH3) = mol NH3 (1 mol N2 )
