So we can not say a glass of water as and energy of so-and-so, but we can say it has an entropy of so-and-so. Calculating Entropy Like we learned for enthalpy, entropy is calculated in a similar manner. That is 4 S is solely determined by 4 S = S products S reactants (23.4) regardless of how the reactants became the products. For example, 4 S for the reaction 2 C 6 H 6 +15 O 2 12 CO 2 +6 H 2 O( 2 3 . 5 ) isthesameasthesumo fthe 4 S ’s for the following reactions 2 C 6 H 6 12 C H 2 (23.6) 12 C H 2 O 2 12 2 H 2 2 3 . 7 ) We can also short cut the Hess’ law calculations by using the
