A 0.4108-g sample of primary-standard Na2 CO3 was treated with 46.50 mL of dilute perchloric acid. The solution was boiled to remove CO2, following which the excess HClO4 was back-titrated with 9.90 mL of dilute NaOH. In a separate experiment, it was established that 26.90 mL of the HC1O4 neutralized the NaOH in a 24.00-mL portion. Calculate the molarities of the HC104 and NaOH. Molarity of the HC1O4 = M Molarity of the NaOH = M
