4.75 An unknown amount of acid can often be determined by adding an excess of base and then "back-titrating" the excess. A 0.3471-g sample of a mixture of oxalic acid, which has two ioniz- able protons, and benzoic acid, which has one, is treated with T00.0 mL of 0.1000 M NaOH. The excess NaOH is titrated with 20.00 mL of 0.2000 M HCI. Find the mass % of benzoic acid. ruse in for
