Using the procedure in Determination of an Equilibrium Constant, a student combines equimolar amounts of acetic acid and ethanol to react as shown by the following equation.

acetic acid + ethanol ethyl acetate + wateracetic acid + ethanol ethyl acetate + water

To determine the initial concentration of acetic acid, 1.00 mL of the resulting mixture was titrated with 0.1105 M NaOH0., requiring 28.75 mL. What is the molarity of the acetic acid?
