Problem: FClO3 is a tetrahedral molecule with chlorine (Cl) at the center. When FClO 3 crystallizes in the solid state, there is no preference for one orientation over another. In other words, the unique F atom ends up randomly distributed among the tetrahedral sites, as shown below.Calculate the expected residual molar entropy S for FClO 3 at 0 K.
