Reference no: EM13118701

A sample of 0.2140 g of an unknown monoprotic acid was dissolved in 35.0 mL of water and titrated with 0.0950 M NaOH. The acid required 27.4 mL of base to reach the equivalence point. (a) what is the molar mass of the acid? (b) after 15.0 mL of base had been added in the titration, the pH was found to be 6.50. What is the Ka for the unknown acid?
