Identify an unknown monoprotic acid. To do that, you take 0.211g of the acid and then titrate it with a 0.0500M solution of NaOH. The pH of the solution after you added 33.64 mL of NaOH is 4.89. The equivalence point is reached after you added 44.70 mL of the NaOH solution.
a) What is the molar mass of the unknown acid?
b) What is the pKa of the acid?
