An analytical chemist weighs out 0.344 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.0700M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 65.5 mL of NaOH solution. Calculate the molar mass of the unknown acid. Round your answer to 3 significant digits. mol X 3 ?
