  1. Dilution Problems

  2. Dilution & Evaporation • Amount of solvent changes • Amount of solute is constant

  3. It’s the same! A portion of the original solution is diluted What can you say about thenumber of solute particlesin pictures b and c?

  4. Molarity Molarity = # of moles of solute Liters of solution Re-arrange: Molarity x Liters of solution = # of moles of solute

  5. Amount of solute is constant Amount of solute in concentrated solution = Amount of solute in dilute solution

  6. MC X VC = MD X VD (C = concentrated D = dilute) MolarityC X VolumeC = MolarityD X VolumeD
