Entropy and temperature of the system

  1. Mar 22, 2007 #1
    1. The problem statement, all variables and given/known data
    ... 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

    2. Relevant equations


    3. 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.
