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. Calculate the molar mass of the unknown

5. The Ka and Molar Mass of a Monoprotic Weak Acid a. Suppose that–unknown to you–the primary standard KHP (potassium hydrogen phthalate, KHC8H4O4) had a potassium iodide impurity of approximately one percent by mass. How would this have influenced the calculated molarity of your sodium hydroxide solution? Would your calculated value be too low, too high, or unchanged? Explain your answer. b. Sketch a typical titration curve for a monoprotic weak acid titrated with a strong base. Label the axes...

35.25 mL of NaOH solution are required to titrate 0.5745 g of an unknown monoprotic acid. Prior standardization of the NaOH determined its concentration as 0.1039 M. 1. Use the data provided to determine the molar mass of the unknown acid 2. If 20 mL of a 1.0 M solution of the unknown monoprotic acid is placed into a beaker and 10 mL of 0.1 M NaOH is added, the pH of the final solution is 1.9. What is the...

A student adds 13.11 grams of propionic acid (a monoprotic acid with molar mass = 74.08 g/mol) to water. When she takes a 25.00 g sample of this solution, and titrates it with 0.1111 M NaOH(aq), she finds that she needs to add 17.17 mL of this solution to reach the endpoint. What was the percent by mass of propionic acid in the solution she made?
