Determining the molar mass of an acid by titration
An analytical chemist weighs out 0.171 g of an unknown triprotic acid into a 250 mL volumetric flask and dilutes to the mark with
distilled water. He then titrates this solution with 0.1100 M NaOH solution. When the titration reaches the equivalence point, the
chemist finds he has added 47.6 mL of NaOH solution.
Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits.
