A 1.00g sample containing benzoic acid and gallic acid is titrated. Benzoic acid has MM=122g/mol and has 1 acidic hydrogen. Gallic acid has MM=170g/mol and has 1 acidic hydrogen. The acid mixtures is dissolved and titrated with 0.500M NaOH solution. To reach the end point in the titration a total volume of 14.71mL of base was needed. What is the mass percent of benzoic and gallic acid?
