kilojoule per kilomole

Molar energyexact by definition

The kilojoule per kilomole is exactly 1 J/mol. It is not a rounding trick: engineering thermodynamics texts work in kilomoles throughout, so enthalpies of formation and gas properties come tabulated in kJ/kmol and the numbers are identical to the chemist's J/mol.

Watch out: The identity is easy to miss and easy to abuse. kJ/kmol equals J/mol, but kJ/mol is a thousand times larger than both. Tables that mix Cengel-style kJ/kmol with chemistry-style kJ/mol are a standard source of factor-of-1000 errors.
