Assuming all the acid to be acetic, calculate the number of grams of acid per 100 mL of vinegar solution. Assuming that the density of vinegar is 1.000, what is the percentage of acetic acid by weight in vinegar? Average your results in the usual manner.
% of Acetic Acid = (mL of NaOH added)(concentration of NaOh)/mL of vinegar sample
