Enter the energy in joules and the amount of substance in moles into the calculator to determine the energy per mole. This calculator helps in converting energy from joules to joules per mole.

## J to J/mol Formula

The following formula is used to convert energy from joules to joules per mole.

E_{m} = \frac{E}{n}

Variables:

• Em is the energy per mole (J/mol)
• E is the energy (Joules)
• n is the amount of substance (moles)

To convert energy from joules to joules per mole, divide the energy value by the amount of substance in moles.

## What is Energy per Mole?

Energy per mole is a way of expressing the energy associated with a certain amount of substance. It is commonly used in chemistry and physics to describe the energy involved in chemical reactions or physical changes per mole of substance. This unit is particularly useful when comparing the energy of reactions involving different amounts of reactants or products.

## How to Calculate Energy per Mole?

The following steps outline how to calculate the energy per mole.

1. First, determine the energy (E) in joules.
2. Next, determine the amount of substance (n) in moles.
3. Use the formula Em = E / n to calculate the energy per mole.
4. Finally, enter the values into the calculator above to verify the result.

Example Problem :

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

Energy (E) = 500 Joules

Amount of Substance (n) = 2 moles
