a 3.54 grams solid sample of an unknown monoprotic acid was dissolved in distilled water to produce a 47.0 mL solution at 25 degrees. This solution was then titrated with 0.2 M NaOH. The equivalence point was reached when 35.72 mL of 0.2 M NaOH was delivered.

Question

A. find the number of moles of acid in the solid sample.

B. Find the molar mass of the unknown acid

C. Find Ka for the unknown acid if the pH at the equivalence point is 8.79

D. What was the pH after 63.2 mL of 0.2 M NaOH was delivered?
