Volume strength (or volume percent) is an outdated term referring to the volume of oxygen gas liberated from one volume of H2O2 solution (at 0°C and 1 atm.).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: X_h = WM_w / (M_h (100 – W) + WM_w)

Where:

M_w = molecular weight of water (18.016)

M_h = molecular weight of H₂O₂ (34.016)

W = weight % of H₂O₂

X_h = mole fraction of H₂O₂
