SUMMARY
The molar binding energy of carbon-12 nuclei is calculated using the mass-energy equivalence formula E=mc². The mass of six protons and six neutrons before binding is 12.09564u, while the mass of carbon-12 after binding is 12u, resulting in a mass defect of 0.009564u. This mass defect can be converted to energy using the conversion factor of 9x10^16 kJ/g. To find the energy per mole, one must account for Avogadro's number, which is approximately 6.022 x 10²³ atoms/mol.
