An analytical chemist weighs out  0.149g  of an unknown diprotic acid into a  250mL  volumetric flask and dilutes to the mark with distilled water. He then titrates this solution with  0.1400M   NaOH  solution. When the titration reaches the equivalence point, the chemist finds he has added  12.8mL  of  NaOH  solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits.
