Consider an isolated spin- paramagnet in an externally applied magnetic field, B. The system has a total of N spins, where n; of the spins are up. (a) Calculate the statistical weight of the state as a function of N and (b) Calculate the entropy of the system in terms of the statistical weight. (c) Find an approximate expression for the entropy when N is a large number using Stirling's formula.
