We’re being asked to calculate the mass of benzoic acid if 29.11 mL of 0.5130 mol/L NaOH was required to reach the equivalence point.
Recall that at the equivalence point of a titration:
Since benzoic acid is a monoprotic acid, there will be just one equivalence point for the titration. This means:
Calculate the mass of benzoic acid (molar mass = 122.12 g/mol) sample titrated if 29.11 mL of a standardized 0.5130 mol/L NaOH solution was required to reach the equivalence point of the titration. Benzoic acid is a monoprotic acid.
a. 0.01493 g
b. 0.2384 g
c. 0.9118 g
d. 1.824 g
e. 3.647 g
