Another student titrated a 0.4799 g sample of unknown monoprotic acid with 0.10336M sodium hydroxide per the procedure in Part II. Using the first derivative curve, the student found the equivalence point volume to be 28.77 mL sodium hydroxide. a. Calculate the number of moles of sodium hydroxide used in the titration. b. How many equivalents of unknown acid were titrated? c. Determine the equivalent mass of the unknown acid
