A 2.411-g sample of a solid, weak, monoprotic acid is used to make 100.0 mL of solution. 25.0 mL of this solution was titrated with 0.06221-M NaOH. The pH after the addition of 30.99 mL of base was 5.32, and the equivalence point was reached with the addition of 45.58 mL of base. a) How many millimoles of acid are in the original solid sample
