Answer #1

The average volume of NaOH solution = (21.48 + 21.43 + 22.53 + 21.39) mL/4 = 21.7075 mL

Now, the no. of millimoles of NaOH = 21.7075 mL * 0.692 mmol/mL = 15.02159 mmol

Concept: At equilibrium, the no. of millimoles of acetic acid = the no. of millimoles of NaOH

Therefore, the no. of millimoles of acetic acid at equilibrium = 15.02159
