Example #2: Determine the K sp of calcium fluoride (CaF 2), given that its molar solubility is 2.14 x 10¯ 4 moles per liter. Solution: It is a simple proportional problem in which we will find either the increased or decreased value of calcium with proportional to Calcium fluoride. Recognize that 3.01 × 10²³ is ½ of Avogadro's number, so you're talking about ½ mol of CaF₂. The molar masses are: Ca = 40.078 grams per mole. Note that, in the given reaction equation, the mole ratio of CaF₂ to Ca is 1:1, so you'll get ½ mol of Ca from this.
