An analytical chemist weighs out 0.059 g of an unknown monoprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.1000M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 12.8 mL of NaOH solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits. g mol X
