Acetic acid is a weak acid.  Its formula is CH3COOH.  Only the last H is an acid proton.  Vinegar is usually 5 % (v/v) acetic acid.  If 25.00 mL of vinegar is titrated by a standardized 0.9315 M NaOH solution, it takes 22.38 mL to reach the endpoint.  Calculate the molarity of acetic acid in the 5 % (v/v) vinegar.
