mole of substance. The unit symbol is written kcal/mol or kcal⋅mol−1. As typically measured, one kcal/mol represents a temperature increase of one degree
(C2H6) is defined as the standard enthalpy change of the process CH3CH2−H → CH3CH2• + H•, DH°298(CH3CH2−H) = ΔH° = 101.1(4) kcal/mol = 423.0 ± 1.7 kJ/mol
not metabolized by the body, it adds very little food energy (14 kJ [3.3 kcal] per gram). In the European Union, it is also known under the E number E955
