It shows the relationship between entropy and the number of ways the atoms or molecules of a thermodynamic system can be arranged.
Accordingly, the Boltzmann equation can be used to solve for entropy.
To get a number for W, you would have to determine the total number of possible states that your molecule or atoms could be in. For a 2-state system, the total number of possible outcomes your system could have is 2^n, where n= the number of atoms. You would typically use this equation to solve for S, which you could use to plug into delta G = delta H - T delta S to determine whether a reaction is spontaneous or not (spontaneous if G is negative).
