At a certain temperature, a saturated solution contains 537 g of NaOH(s) per liter of solution. Calculate the molarity of this saturated NaOH(aq) solution.
Use a combination of balanced chemical equations and their K's to calculate the equilibrium constant for the titration of formic acid with NaOH, which you used in the previous question. (Hint: You will need to include the value of Kw at some point..
To learn how to calculate the solubility from Ksp and vice versa. Consider the following equilibrium between a solid salt and its dissolved form (ions) in a saturated solution:
