The volume strength of 1.5 N H2O2 is.......

  • Chemistry stochimetry2 -

    One molar of H2O2 is two normal.

    So 1.5N is 0.75M.

    The volume strength of a hydrogen peroxide solution is the volume of oxygen gas that can be liberated by decomposing one litre of the solution (at standard temperature and pressure).

    1 mole of O2 occupies 22.4L at STP.

    2 H2O2(aq) = 2 H2O(l) + O2(g)

    Find how many litres of O2 can be liberated by 1 litre of 1.5N H2O2.
