### 9.25, Calculation

"9.25 If SO2F2 adopts a positionally disordered arrangement in its crystal form, what might its residual molar entropy be?"

When calculating entropy using S=k(b)lnW, the solutions manual states that W is 6^(6.02214*10^23). Is the exponent just based on the number of molecules/units involved in the reaction?

Yes, since the Boltzmann Formula relates entropy and how the molecules arrange in said micro-states:

Thus 6 ^ avogadro's number would be W.
