Calculate the entropy of a sample of a solid in which it is supposed that a substituted benzene molecule, C6H5F, may be found in any one of six orientations with the same energy at T=0. Suppose there is 1.0 mol of molecules in the sample.

Why is one mole of the molecule multiplied with the equation?

It tell you that there is 1mol of the substance. W= number of possible orientation^number of particles in 1 mol (which is Avogrado's number)
Then use S=kB*lnW to find the entropy of the sample.

Return to “Third Law of Thermodynamics (For a Unique Ground State (W=1): S -> 0 as T -> 0) and Calculations Using Boltzmann Equation for Entropy”
