Molar Enthalpy Calculator

Formula

The formula to calculate the molar enthalpy is:

\[ E_m = \frac{\Delta H}{n} \]

Where:

\( E_m \) is the Molar Enthalpy (J/mol)
\( \Delta H \) is the Total Change in Enthalpy (J)
\( n \) is the Total Number of Moles

What is Molar Enthalpy?

Molar enthalpy is defined as the enthalpy change per mole of a substance. It is an important concept in thermodynamics and chemistry for understanding the energy changes during chemical reactions.

Example Calculation

Let's assume the following values:

Total Change in Enthalpy (ΔH): 5000 J
Total Number of Moles (n): 2 mol

Using the formula to calculate the molar enthalpy:

\[ E_m = \frac{5000}{2} = 2500 \text{ J/mol} \]

The molar enthalpy is 2500 J/mol.
