## Percent Mixture Formula

The following formula is used to calculate a percent mixture:

PM = X / Y * 100

- Where PM is the percentage mixture
- X is the mass/volume/etc of the substance
- Y is the mass/volume/etc of the solution

To calculate a percent mixture, divide the mass or volume of the substance by the mass or volume of the total solution or object, then multiply by 100.

In the case of this formula, mass, volume, or any other unit of measure could be used in determining the percent mixture.

## Definition

**What is a percent mixture? **

A percent mixture is a term used to describe the ratio of one individual substance in a greater mixture of other substances. These are most often compounds within a solution, but they could also be solid objects in a mixture of other solid objects.

## Example Problem

**How to calculate the percent mixture? **

In this example, we will be using quantities of substance and solution in determining a percentage mixture. These quantities are simply numbers of objects, but they could be substituted for mass or volume or another unit of measure.

First, determine the amount of the substance in the mixture. For this example, there are 200 of the substance in question.

Next, determine the total amount of the mixture. The mixture in this case is 400.

Finally, calculate the percent mixture of the substance using the formula above:

PM = X / Y * 100

PM = 200 / 400 * 100

PM = 50%
