An analytical chemist weighs out  0.019g  of an unknown monoprotic acid into a  250mL  volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with  0.1400M   NaOH  solution. When the titration reaches the equivalence point, the chemist finds she has added  2.6mL  of  NaOH  solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits.
