19.32 mL of .500 M NaOH solution is required to exactly neutralize a 10.00mL sample of vinegar. Assuming that all acidity of vinegar is attributable to acetic acid(HC2H3O2) what is the percent by weight of acetic acid in vinegar? The density of the vinegar is 1.006g/mL. The chemical equation for the neutralization reaction is NaOH+HC2H3O2(aq)=NaC2H3O2+H2O.
