A supply of glacial acetic acid (monoprotic acid, C2H4O2) has absorbed water from the atmosphere. We need an assay to determine the mass % of acetic acid in a sample that absorbed water. 4.274g of a sample containing acetic acid is dissolved in a 50.08mL volumetric flask; then 14.84mL of the dilution is titrated with 0.211M of aqueous NaOH (aq). It required 10.14mL to reach the equivalence point. Calculate the mass % of acetic acid in the contaminated sample.
