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.

1. First, determine the density of the substance (D) in g/cm³.
2. Next, determine the volume of the substance (V) in cm³.
3. Next, gather the formula from above = n = (D * V) / MW.
4. Finally, calculate the number of moles (n).
5. 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
