Enter the density and volume of the substance into the calculator to determine the number of moles.

## Density To Moles Formula

The following formula is used to calculate the number of moles from density.

n = (D * V) / MW

Variables:

- n is the number of moles (mol)
- D is the density of the substance (g/cm³)
- V is the volume of the substance (cm³)
- MW is the molecular weight of the substance (g/mol)

To calculate the number of moles, multiply the density of the substance by its volume. Then, divide the result by the molecular weight of the substance.

## What is Density To Moles?

Density to moles refers to the conversion process used in chemistry to determine the number of moles in a substance based on its density. The density of a substance is its mass per unit volume, while a mole is a unit of measurement used in chemistry to express amounts of a chemical substance. By knowing the density and the molecular weight of a substance, one can calculate the number of moles. This conversion is often used in stoichiometry, the calculation of quantities in chemical reactions.

## How to Calculate Density To Moles?

The following steps outline how to calculate the number of moles using the Density To Moles formula.

- First, determine the density of the substance (D) in g/cm³.
- Next, determine the volume of the substance (V) in cm³.
- Next, gather the formula from above = n = (D * V) / MW.
- Finally, calculate the number of moles (n).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

density of the substance (D) = 2.5 g/cm³

volume of the substance (V) = 50 cm³

molecular weight of the substance (MW) = 32 g/mol
