Chapter 4, Problem 76PS

Vitamin C has the formula C₆H₈O₆. Besides being an acid, it is a reducing agent. One method for determining the amount of vitamin C in a sample is to titrate it with a solution of bromine, Br₂, an oxidizing agent.

C₆H₈O₆(aq) + Br₂(aq) → 2 HBr(aq) + C₆H₆O₆(aq)

A 1.00-g "chewable" vitamin C tablet requires 27.85 ml of 0.102 M Br₂ for titration to the equivalence point. What is the mass of vitamin C in the tablet?
