again sorry i need help to solve this problem.. thanks a lot
a 0.4793g sample of primary standard grade Na2CO3 was treated with 40ml of dilute perchloric acid. the solution was boiled to remove C02 following which the excess HClO4 was back titrated with 8.70ml of dilute NaOH. in a separate experiment, it was established that 27.43ml of HClO4 was needed to neutralize 25ml of the dilute NaOH solution. Calculate the molarities of the NaOH and perchloric acid solution.
