please answer all parts to question 2. thanks.

2. Consider the solubility equilibrium for CaF2 : CaF2(s)Ca2+(aq)+2F(aq) Neglect ion pairing and calculate the following, using the Davies equation to estimate ionic activity coefficients: a) Estimate the molality of calcium ions in a saturated solution of calcium fluoride at 25C. Use table 2C.7 in the textbook appendix for relevant thermodynamic data. b) Estimate the molality of calcium ions in a saturated solution of calcium fluoride dissolved in 0.100mKNO3 at 25C. c) Estimate the molality of fluoride ions in a saturated solution of calcium fluoride dissolved in 0.100mCa(NO3)2 at 25C
