9. A solution of vinegar contains an unknown amount of acetic acid, HC2H302. A 25.0 mL sample of vinegar is titrated with a 0.650M NaOH according to the chemical reaction shown above. If it requires
32.04 mL of the titrant to reach the equivalence point, what is the concentration of HC2H502 in the
vinegar?
