An analytical chemist weighs out of an unknown monoprotic acid into a volumetric flask and dilutes to the mark with distilled water. he then titrates this solution with solution. when the titration reaches the equivalence point, the chemist finds he has added of solution. calculate the molar mass of the unknown acid. be sure your answer has the correct number of significant digits.

Which of the following statements about acidic water is true? a. acid has no effect on the h,o molecules. b. the solution contains a larger number of oh ions than h,o ions. c. the solution contains a larger number of h,o ions than qh ions. d. the solution contains an equal number of h,o ions and oh ions. none of the above e.
