I am attempting to determine the Ksp of Ca(OH)2 via gravimetric analysis. 0.014 g of solid Ca(OH)2 was found to be remaining out of a 20mL of Ca(OH)2 solution. How can I use this to determine the Ksp of the Ca(OH)2?

13. Calculate the value for the equilibrium constant, Ksp for the following reaction. Ca(OH)2 (s) Ca+2 (aq) + 2 OH- ⇆ (aq) assume that a 20.00 mL sample of saturated Ca(OH)2 was titrated with a 0.050 M standard HCl solution to the equivalence point. Assume that 8.1 mL of standard HCl was needed to get to the equivalence point. (I am having trouble with this one. Let me know if there is additional information needed)

You are using gravimetric analysis to determine the concentration of calcium (Ca2+) in tap water. The calcium is precipitated as calcium oxalate monohydrate upon addition of ammonium oxalate to the tap water according to the following reaction: Ca +2 (aq) + C2O4 -2 (aq) → CaC2O4 ∙H_2 O (s) Ksp = 1.3 x 10 -8 The protocol calls for addition of 25 mL of 1.0 M ammonium oxalate to 25 mL sample.

A 25.00 g solid sample of Ca(OH)2 was added into 1250 mL of 0.400 M HCl aqueous solution. The temperature of the solution was decreased from 36.6oC to 20.0oC. Assuming the final volume of the solution is 1250 mL / the density of the solution is 1.000 g/mL / the heat capacity of the solution is 4.18 J/(oC*g). Please determine the molar heat of the reaction of the limiting reactant.
