Volume strength (or volume percent) is an outdated term referring to the volume of oxygen gas liberated from one volume of H2O2 solution (at 0°C and 1 atm.).

Mole fraction calculated from: Xh = WMw / (Mh (100 – W) + WMw)

Where:

Mw = molecular weight of water (18.016)

Mh = molecular weight of H2O2 (34.016)

W = weight % of H2O2

Xh = mole fraction of H2O2
