(a) Strontium fluoride, SrF2, has a Kspvalue in water of 2.45 × 10-9at room temperature. Calculate the solubility of SrF2in water. Express your answer in units of molarity.
(b) Calculate the solubility of SrF2in 0.03 M NaF (aq). Express your answer in units of molarity. Assume that NaF is completely dissociated in water.
