An analytical chemist weighs out 1.300 grams of an unknown monoprotic acid into a 250 mL volumetric flask and dilutes to the mark. The chemist then obtains 100 mL of the solution and titrates the 100mL of the solution with 0.1 M NaOH. When the titration reaches the equivalence point, the chemist finds he has added 24.50 mL of NaOH solution.
