17.61 mL of Na2S2O3 was used to titrate 1 mL of commercial H2O2 solution. The concentration of Na2S2O3 is 0.1002 M.Assuming the density of solution is 1g/mL? What is mass percentage of H2O2 solution? (MW of H2O2 = 34.01 g/mol)
The overall equation for the chemical reaction is shown below
​H2O2 + 2 H+ + 2 S2O3-2 → S4O6-2 + 2 H2O
