Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid dissociates in water: C6H5COOH (aq) + H2O (l) C6H5COO- (aq) + H3O+ (aq) The pKa of this reaction is 4.2. In a 0.62 mol L^-1 solution of Benzoic acid, what percentage of the molecules are ionized? Express your answer to two significant figures and include appropriate units.
