1. WARM UP Compare and contrast the terms unsaturated, saturated, and supersaturated using a Triple Venn diagram.

2. Concentration

3. Concentration Units Molarity – Moles of solute Liters of solution – Unit: M

4. Concentration Units Molality – Moles of solute Mass of solvent (kg) – Unit: m

5. Concentration Units Mole Fraction – Moles of solute Moles of all components – No unit

6. Concentration Units Percent by Mass – Mass of solute Mass of solution Mass of solution = solute + solvent – Unit: % x 100

7. Conversions Can convert into needed units Can convert to desired unit

8. Conversions Can solve for any of the three terms in equation Can convert one unit into another

9. WRAP UP Calculate the percent by mass and mole fraction of a solution, using the following data: 12.8 g of LiOH mixed with 93.4 g of water
