1. The problem statement, all variables and given/known data Lithium phosphate, Li3PO4, has a solubility product Ksp = 2.37 × 10-4. What is the concentration of Li+ ions in a saturated solution of Li3PO4? 3. The attempt at a solution What is the initial concentration of Lithium? Or does it matter? I got 0.163 M but answer says 0.0544 M Without it I can't do it!! Somebody please help. Thanks.
