Volume fraction, a chemical term, refers to the percentage of the volume of solute (liquid) in the total solution volume. At a certain temperature and pressure, the volume of pure substance B is divided by the sum of the volumes of each component of the mixture, V.[1]
Volume fraction φ B is defined as the volume of pure substance B at a certain temperature and pressure
Divide by the sum of the volumes of each pure substance in the mixture, V.[2]

For the solution with liquid solute, ignore the volume change during miscibility, and divide the volume of solute by the volume of solution during calculation.For example, sterilized alcohol φ（
）=0.75 means that 75 ml pure ethanol is added with water to 100 mL to prepare.[3]
