1. 15-2: Concentration of Solutions

2. Concentration Amount of solute in a given solvent or solution Types:
Molarity
Molality
Mole fraction

3. Concentration Vocab
Saturation: no more solute can be dissolved under existing conditions of temperature and pressure
Unsaturated: a soln that contains less than the maximum amount of solute
Supersaturated: unstable solns that contain more solute than normally allowed to make it saturated

4. Molarity Molarity (M) = moles solute liters solution
Is somewhat dependent on temperature
SP #1, pg. 507
PP 1 and 2

5. Volumetric Flasks
How do they work?

6. Molality Molality (m) = moles solute kg solvent
Does not depend on temperature
SP #2, pg. 508
PP 3 and 4

7. Mole Fraction (X) = moles component
Total moles
SP #3
PP 5 and 6
