Units of S and H

[MCracchiolo 1C]

When calculating problems that involve DeltaS and DeltaH, if you multiply the standard enthalpies of formation or standard molar entropies by the number of moles in the balanced chemical equation, why are your answers still in kJ/mol and J/(K*mol)?

[Nickolas Manipud 1C]

Because you just found the standard enthaply or molar entropy of 1 mole of some substance from the chemical reaction

I'm pretty sure Dr. Lavelle said that he would accept either unit. However, for enthalpy of formation or standard molar entropy or Gibbs free energy of formation, it must be per mole because that's the definition of "formation".

[Yixin Angela Wang 2H]

I think the per mole part can be omitted, at least that's what I recall Dr. Lavelle saying. At least for this class.

Hi Megan!
Although sometimes understanding the units can be quite difficult, in class, Dr. Lavelle mentioned either unit would be correct.
Just be sure to make the units for your Gibbs Free Energy of formation to be in "per mole".
Good luck!
