  1. MOLARITY

  2. Molarity (M) Molarity (M) = moles of solute liters of solution

  3. # of grams  by FM x by FM # of moles Recall the mole map!

  4. Rearranging … Molarity (M) = # moles of solute liters of solution liters of solution = # of moles solute Molarity # moles of solute = (Molarity)(litersof soln)

  5. Word ProblemTwists • sometimes give moles of solute; sometimes give grams of solute gramsmust beconverted to moles • sometimes give mL of solution instead of Liters millilitersmust be converted to liters • sometimes ask for: • grams/moles/volume of solute rather than molarity
