Ksp

Q. A chemist adds solid NaF to a flask containing 100.0 mL of 0.00020 Ba(NO3)2. What minimum mass (g) of NaF must be added before a precipitate forms? (i.e. what mass would form a saturated solution?) Ksp for BaF2 is 2.4 × 10-5 and the molar mass of NaF is 41.99 g/mol. Assume solution volume does not change as NaF is added.
