22.Concentrated hydrogen peroxide solutions are explosively decomposed by traces of transition metal ions (such as Mn or Fe) by the following reaction: 2H2O2(aq)  2H2O(l) + O2(g). What volume of pure oxygen gas collected at 27 C and 764 torr, would be generated by decomposition of a 50.0 % by mass hydrogen peroxide solution? (The hydrogen peroxide solution is 50.0 % pure.)
