From Boltzmann's equation of entropy:

#nbarS = k_BlnOmega# where:

#barS# is the molar entropy of the chosen ensemble of molecules.#k_B = 1.3807xx10^(-23)# #"J/K"# is the Boltzmann constant.#Omega# is the number of microstates available, consistent with the system's macrostates.

Solving for

#color(blue)(Omega = e^(nbarS"/"k_B))#

Thus, if you know the molar entropy of a compound, you can find the number of microstates it has in however many
