Avinegar solution of unknown concentration was prepared by diluting 10.00ml of vinegar to a total volume of 50.00ml with deionized water.
a 25.00 ml sample of a diluted vinegar solution required 20.78 ml of 0.1032 m naoh to reach the titration equivalence point.

calculate the concentration of acetic acid (ch3cooh) in the original vinegar solution (before dilution).a. 4.289 x 10^-4 mb. 2.144 x 10^-3mc. 8.578 x 10^-1md. 4.289 x 10^01m
