1. Concentration of Solution
Concentration refers to the amount of solute dissolved in a solution.

2. *MOLARITY

3. Example: Describe how you would prepare 2. 50 L of 0
Example: Describe how you would prepare 2.50 L of M Na2SO4 solution starting with: a) solid Na2SO4 b) 5.00 M Na2SO4
Dissolve 236 g
of Na2SO4 in
enough water
to create 2.50 L
of solution.

4. MOLARITY BY DILUTION
When you dilute a solution, you can use this equation:

5. Add 0.333 L of Na2SO4 to 2.17 L of water.
Example: Describe how you would prepare 2.50 L of M Na2SO4 solution starting with: a) 5.00 M Na2SO4
Add L of Na2SO4 to 2.17 L of water.

6. MASS PERCENT

7. MASS PERCENT
Example: What is the percent of NaCl in a solution made by dissolving 24 g of NaCl in 152 g of water?

8. *MOLALITY

9. MOLALITY
Example: What is the molality of a solution that contains 12.8 g of C6H12O6 in g water?

10. MOLALITY
Example: How many grams of H2O must be used to dissolve 50.0 g of sucrose to prepare a 1.25 m solution of sucrose, C12H22O11?
