A 25 ml of an HClO₄ solution was titrated with 0.1032 M NaOH solution, 28.06 ml was added in excess, and it took 3.47 ml of 0.1094M HCl to back titrate the excess NaOH, calculate the molar concentration of the HClO₄

A 25 ml of an HCIO4 solution was titrated with 0.1032 M NaOH solution, 28.06 ml was added in excess, and it took 3.47 ml of 0.1094M HCI to back titrate the excess NaOH, calculate the molar concentration of the HCIO4
