Entropy and temperature of the system

  • #1

Homework Statement

... Show that the entropy of the system in the microcanonical ensemble is

[tex] W = \frac{N!}{n!(N-n)!}3^n [/tex]

and obtain an expression for the temperature of the system. ...
N = number of molecules
n = number of molecules in orthostate

Homework Equations

The Attempt at a Solution

This question makes no sense, right? Because it says the entropy is W which is just a number, and entropy is in the units Joule/Kelvin

It should probably be reworded. But entropy is defined as k_b*log(S) where S is the number of states corresponding to a given macroscopic state. The interesting quantity in the entropy is S and it looks like that's what they want you to find.
