(D) The entropy change for a phase transition is given by the formula $\Delta S = \frac{q_{rev}}{T}$.For the melting of ice,the heat absorbed is $q = m \times L_f$,where $m = 27.3 \ g$ and $L_f = 330 \ J g^{-1}$.$q = 27.3 \ g \times 330 \ J g^{-1} = 9009 \ J$.The melting temperature of ice is $T = 0^{\circ} C = 273 \ K$.Therefore,$\Delta S = \frac{9009 \ J}{273 \ K} = 33 \ J K^{-1}$.
