A sample of vinegar is analyzed to determine its acetic acid concentration as mass percent. an analyze is prepared by diluting 15 mL of the original vinegar to 100 mL in a volumetric flask. Then, a 25 mL aliquot of this analyze is titrated with 0.1022M NaOH. if the titration endpoint is 31.23 mL, calculate the mass percent of acetic acid in the original sample.

KOH (concentration = 0.2205 M) is used in a titration to determine the amount of acetic acid (CH3COOH) in vinegar! 50 mL of vinegar was diluted to 500 mL in a volumetric flask. 25 mL of the diluted vinegar solution was titrated five times with the KOH. The concentration of acetic acid in the DILUTED vinegar sample is 0.2171 M Calculate the concentration of acetic acid in the ORIGINAL vinegar solution Give your answer in g/L MM CH3COOH = 60.05...
