A 25.0-mL sample of vinegar (which contains the weak acid acetic acid, CH 3 CO 2 H) requires 28.33 mL of a 0.953 M solution of NaOH for titration to the equivalence point. What is the mass of acetic acid (molar mass = 60.05 g/mol), in grams, in the vinegar sample, and what is the concentration of acetic acid in the vinegar? CH 3 CO 2 H(aq) + NaOH(aq) → NaCH 3 CO 2 (aq) + H 2 O(l)
