Question 25 3.5 pts A 0.258-g sample of a pure triprotic acid, H3A, (where A is the generic anion of the acid), was dissolved in water and titrated with 0.150 M barium hydroxide solution. The titration required 13.9 mL of the base to reach the equivalence point. What is the molar mass of the acid ? 227 g/mol 82.5 g/mol 371 g/mol 124 g/mol 186 g/mol Question 24 1.5 pts Which of the following compounds would have...
