The **dilution factor** is a term used in chemistry and biology to describe the ratio of the volume of the original substance or stock solution to the volume of the solvent added to achieve a desired concentration. It’s a way to quantify how much a solution has been diluted.

In today’s article we are going to share complete general information about Dilution factor and it’s example and how do you calculate it.

## Definition of Dilution

Dilution involves adding more solvent to a solution without increasing the amount of solute. This process reduces the concentration of the solute in the solution. The dilution factor can be expressed as a ratio or, less commonly, as an exponent. For example, a dilution factor of 1:5 means that 1 unit volume of solute is combined with 4 unit volumes of solvent, resulting in a total of 5 unit volumes.

## Examples of Dilution Factor

Here are a few examples to illustrate the concept of dilution factor:

**Example 1**: If you have 1 mL of a stock solution and you add 9 mL of water to it, your final solution is 10 mL. The dilution factor is 10, meaning the original solution has been diluted 10 times.**Example 2**: For a 1:250 dilution in 500 mL, you would take 2 mL of your stock solution and add enough solvent to reach a final volume of 500 mL. The dilution factor here is 250.

## How to Calculate Dilution Factor

The calculation of the dilution factor is straightforward. It’s the final volume ((V_f)) divided by the initial volume ((V_i)) of the solution. The formula is:

*Dilution Factor (DF)=Vi/Vf*

For instance, if you add 0.1 mL of a specimen to 9.9 mL of diluent, the final volume is 10 mL. The dilution factor would be:

**DF=0.1 mL10.0 mL=100**

This means the sample has been diluted by a factor of 100.
