Molar Enthalpy Calculator
How much energy is involved in chemical processes? Calculate it by using the Molar Enthalpy Calculator. Enter specific values like the total enthalpy or the number of moles into the calculator to determine the molar enthalpy.
What is Molar Enthalpy?
Molar Enthalpy is the amount of energy change per mole of substance during a chemical reaction. It’s a key concept in thermodynamics and help you to understand energy changes in reactions.
How to Use the Calc ?
1. Total Change in Enthalpy (J): Input the total change in enthalpy.

 Example: 1000 J
2. Total Number of Moles: Enter the total number of moles involved in the process.

 Example: 2 moles
3. Molar Enthalpy (J/mol): Provide the molar enthalpy.

 Example: 500 J/mol
Example Usage
 Total Change in Enthalpy: 1000 J
 Total Number of Moles: 2 moles
 Molar Enthalpy: 500 J/mol
When you fill in these values and click “Calculate,” the calculator will compute the missing value.
Formula
The formula to calculate Molar Enthalpy (${E}_{m}$) is:
${E}_{m}=\frac{\mathrm{\Delta}H}{n}$
Variables
Variable  Description 

${E}_{m}$  Molar Enthalpy (J/mol) 
$\mathrm{\Delta}H$  Total Change in Enthalpy (J) 
$n$  Total Number of Moles 
How To calculate Molar Enthalpy
Example 1
For example your input is:
 Total Change in Enthalpy ($\mathrm{\Delta}H$): 1000 J
 Total Number of Moles ($n$): 2 moles
Calculation:
1. Plug the values into the formula:
${E}_{m}=\frac{1000\text{J}}{2\text{moles}}$
2. Calculate the molar enthalpy:
${E}_{m}=500\text{J/mol}$
Example 2
For example your input is:
Given Values:
 Total Change in Enthalpy ($\mathrm{\Delta}H$): 2000 J
 Total Number of Moles ($n$): 4 moles
Calculation:
1. Plug the values into the formula:
${E}_{m}=\frac{2000\text{J}}{4\text{moles}}$
2. Calculate the molar enthalpy:
${E}_{m}=500\text{J/mol}$
