An analytical chemist weighs out 0.108 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 0.1300M NaOH solution. When the titration reaches the equivalence point, the chemist finds he has added 25.4 mL of NaOH solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits. 0 g mol x10 X
