Density to Moles Calculator

Formula

To calculate the number of moles from density:

\[ n = \frac{D \cdot V}{MW} \]

Where:

\(n\) 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)

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.

Example Calculation 1

Let's assume the following values:

Density (\(D\)) = 1.5 g/cm³
Volume (\(V\)) = 100 cm³
Molecular Weight (\(MW\)) = 50 g/mol

Using the formula:

\[ n = \frac{1.5 \cdot 100}{50} = 3 \]

The number of moles is 3 moles.

Example Calculation 2

Let's assume the following values:

Density (\(D\)) = 2 g/cm³
Volume (\(V\)) = 200 cm³
Molecular Weight (\(MW\)) = 100 g/mol

Using the formula:

\[ n = \frac{2 \cdot 200}{100} = 4 \]

The number of moles is 4 moles.
