Volume percent (v/v %) is defined as:
volume percent = [(volume of solute) / (volume of solution)] x 100%
Volume percent is handy when preparing solutions of liquids. Concentration of a solution can be stated in volume percentages.
Be aware that volume of solution is in formula denominator, not volume of solvent. Thus to get 10% v/v solution of ethanol in water you can take 10 ml of ethanol and add enough water to have total 100 ml of resulting solution.
It is worth to mention volumes of solute and solvent cannot be simply added to get volume of solution. For instance if you add 10 ml of ethanol to 90 ml of water the volume of the solution will be less than 100 ml.
