The product of the number of moles and the enthalpy change in kJ/mol has the units kJ: (number of moles) ( in kJ/mol) = kJ. We therefore report in kJ. 21.04.2011 The units for the molar heat of fusion are kilojoules per mole (kJ/mol).

If 10 moles of liquid water was produced from molecular hydrogen gas and molecular oxygen gas, then 10 × 285.8 = 2858 kJ of energy would be released. To get the energy for one molecule in J, divide the kJ mol-1 value by Avogadro's number, 6.022 x 10*23 mol^-1 then x10^3 J, or to go from J to kJ mol-1 multiply by 6.022 x 10*23 mol^-1 to get to J mol-1 and then divide by 10^3 to go from J mol-1 to kJ mol-1.

A hartree is equal to 2625.5 kJ/mol, 627.5 kcal/mol, 27.211 eV, and 219474.6 cm-1. The energy reported from a calculation is the energy for the separation of the molecule to nuclei and electrons. This released or required energy is measured by the use of enthalpy of formation or standard enthalpy.
