A 530-g quantity of ethanol, in the liquid state at its melting point of -114°C, is frozen at atmospheric
pressure. The heat of fusion of ethanol is 1.04 × 105 J/kg, the molecular mass is 46.1 g/mol, and the ideal gas constant is R = 8.314 J/(mol·K). The change in the entropy of the ethanol as it freezes is closest to (a) -350 J/K (b) -390 J/K (c) -320 J/K (d) 320 J/K or (e) 350 J/K. Thank you for explaining!
