15-2: Concentration of Solutions

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

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

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

Volumetric Flasks How do they work?

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

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