Molar Entropy

How can you tell the molar entropy of a substance and what does it mean?

The molar entropy is basically the entropy per mole of a substance. If you want to find the molar entropy, you need to know how many possible positions the molecules has as in number 25. Then, you have an exponent with Avagadoros number. You plug all this in the boltzman equation and you should be good to go :)

Another questioned was asked about molar entropy, and I found this helpful: the word "molar" is clear to show that we need Avogadro's number in our equation, because it is the number of units in one mole of any substance. And because the molar entropy is the entropy of one mole of a substance, we need to have Avogadro's number as the exponent.
