Strength of aqueous solution of H₂O₂ is expressed in ‘volume’ units i.e., volume strength.
The commercially marketed 30% (by mass) solution of H₂O₂ has volume strength of 100 volume.
It means that 1 mL of 30% solution of H₂O₂ will give 100 mL oxygen at STP.

Thus, Volume strength refers to the volume of oxygen (O₂) in litres at STP obtained by decomposition of 1 litre of the sample.
