4) A 810-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 x 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) -540 J/K; B) -490 J/K; C)-600 J/K; D) 490 J/K; E) 540 J/K. 5) Propane gas (C3H8) behaves like an ideal gas with y=1.127. Determine the molar heat capacity at constant pressure. A) 43.89 J/mol K; B) 57.185 J/mol K; C) 65.5 J/mol K; D) 73.8 J/mol K; E) 8.315 J/K.
