Suppose a compound could point in any of four directions in the solid and still have the same energy. What would be the total entropy (J/K) of orientation if 8.8570e+18 molecules are randomly distributed? Key Concept:Boltzmann's relationship, S = klnW, is a probability equation that relates the entropy to the number of ways an atom or molecule can orient itself. This is the entropy of one particle. You may have to multiply by the number of atoms (molecules) to figure out the entropy of a larger number of particles.
