The average millimoles of NaOH = 0.25*(32+33+32)/3 = 8.08 mmol
The average millimoles of CH3COOH = 100*0.808 = 80.8 mmol
i.e. The moles of CH3COOH actually consumed in the reaction with NaOH = 8.08 mmol
Note: NaOH is a limiting reactant.
Here, the % by weight = 80.8/8.08 = 10%
Which is not matching with the manufacturer's claim (5%).
