Specific Enthalpy (Esp) Calculator

Calculate Specific Enthalpy (Esp)





Formula

The formula to calculate the Specific Enthalpy (Esp) is:

\[ \text{Esp} = \frac{\Delta H}{\text{mm} \cdot N} \]

Where:

Definition

Example

Let's say the change in enthalpy (dH) is 5000 J, the molar mass (mm) is 18 g/mol, and the number of moles (N) is 2. Using the formula:

\[ \text{Esp} = \frac{5000}{18 \cdot 2} \approx 138.89 \, \text{J/g} \]

So, the Specific Enthalpy (Esp) is approximately 138.89 J/g.
