An analytical chemist weighs out 0.130 g of an unknown monoprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. He then titrates this solution with 0.0800M NaOH Solution. When the titration reaches the equivalence point, the chemist finds he has added 22.5 mL of NaOH Solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits. 0 mol X

A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 30. mg of oxalic acid (H,C,0,), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 62.3 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits. x10

An analytical chemist weighs out 0.406 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 0.1400M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 34.9 mL of NaOH solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits. C mol Explanation Recheck JAHE B!
