It is customary to indicate the strength of a sample of `H_(2)O_(2)` under specification of volume. The strength of `H_(2)O_(2)` solution can also be in %(w/v) or molarity or normality,"10 Vol `H_(2)O_(2)` solution means I ml of`H_(2)O_(2)` solution decomposes to give 10 ml of `O_(2)` gas at STP. 1 lit of `H_(2)O_(2)` solution decomposes to give 10 lit of `O_(2)` gas at STR.
