An analytical chemist weighs out 0.413 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.1700 M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 29.2 mL of NaOH solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits. 0 H mol Explanation Check Type here to search x10 X O B H Ⓒ2022 McGraw Hill LLC.

An analytical chemist weighs out 0.413 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with
distilled water. She then titrates this solution with 0.1700 M NaOH solution. When the titration reaches the equivalence point, the
chemist finds she has added 29.2 mL of NaOH solution.
Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits.
