    Any help with the following would be greatly appreciated...

    Aqueous hydrogen peroxide has concentration: "100-volume". (what does that mean, guys?)
    Plan 2 different accurate methods of determining the concentration of H2O2 in "100-volume" hydrogen peroxide. One method must be titration.
    And must include how to caluculate the conc from each method.

    Thankss!

    100 vol means that that is how much O2 would be given out if it were to be totally decomposed.
