What is volume percent?

Volume percent (v/v%) is volume of solute divided by total volume of solution, times 100. It is used for alcohol content in beverages.

Why might volumes not be additive?

Intermolecular forces can cause the total volume to differ from the sum of individual volumes when mixing different liquids.

How do you convert volume percent to molarity?

Molarity = (v/v% × 10 × density) / molar mass, where density is in g/mL.

How to Calculate Volume Percent

Formula

Volume % = (volume of solute / volume of solution) × 100

Commonly used for liquid-in-liquid solutions such as alcohol in water.

Example Calculation

30 mL of ethanol in 100 mL of solution.

01Volume % = (30 / 100) × 100
02Volume % = 30%
