We dissolve 2.77 g of an unknown acid, HA, in enough water to produce 25.0 mL of solution. The pH of this solution of HA(aq) is 1.33. We titrate this solution with a 0.250 M solution of NaOH. It takes 44.0 mL of the NaOH solution to reach the equivalence point.

(a) What is the molar mass of HA?

(b) What is the pK_a value of HA(aq)?

(d) What is the pH one third along the titration when you still have twice as much HA(aq) as A^-(aq)?
