The standardized NaOH solution was determined to be 120M whereas the mass of the sample of impure tartaric acid was 1.35g. If the initial reading of the buret volume changed from 48 ml to a final reading of 17 ml at the endpoint of the titration of the impure sample calculate the percent of pure tartaric acid in the unknown mixture.
