Enter the volume of the substance (mL) and the volume of all substances (mL) into the Volume Fraction Calculator. The calculator will evaluate and display the Volume Fraction.

## Volume Fraction Formula

The following formula is used to calculate the Volume Fraction.

Vf = Vs / Va

• Where Vf is the Volume Fraction (mL/mL)
• Vs is the volume of the substance (mL)
• Va is the volume of all substances (mL)

## How to Calculate Volume Fraction?

The following example problems outline how to calculate Volume Fraction.

Example Problem #1:

1. First, determine the volume of the substance (mL).
1. The volume of the substance (mL) is given as: 40.
2. Next, determine the volume of all substances (mL).
1. The volume of all substances (mL) is provided as: 100.
3. Finally, calculate the Volume Fraction using the equation above:

Vf = Vs / Va

The values given above are inserted into the equation below:

Vf = 40 / 100 = .40 (mL/mL)

Example Problem #2:

The variables needed for this problem are provided below:

volume of the substance (mL) = 90

volume of all substances (mL) = 180

Entering these values and solving gives:

Vf = Vs / Va = .50 (mL/mL)
