It is customary to indicate the strength of a sample of H_2O_2under specification of volume. The strength of H_2O_2solution can also be in %(w/v) or molarity or normality. 10 vol H_2O_2 solution means Iml of H_2O_2solution decomposes to give 10ml of O_2gas at STP. 1 lit of H_2O_2solution decomposes to give 10 lit of O_2gas at STP.The volume strength of 15%(w/v) solution of hydrogen peroxide is
