### Units of entropy

I had always thought that the units for entropy was: joules/moles x kelvin
But is it possible for it to be just:
joules/kelvin?

Yes it is possible. Entropy can be equal to q/T, and the units for q is Joules and Kelvin for T, so the units of your answer can be Joules/Kelvin.

If the problem asks for entropy per unit of a substance, it would be J/(K*mol) or J/(K*mol) if it's per unit mass. Otherwise you can probably assume they just want the answer in J/K.
