The standard molar entropy of solid hydrazine at its melting point of 1.53 C is 67.15 J

Question:

The standard molar entropy of solid hydrazine at its melting point of 1.53 °C is 67.15 J mol-1 K-1. The enthalpy of fusion is 12.66 kJ mol-1. For N2H4(l) in the interval from 1.53 °C to 298.15 K, the molar heat capacity at constant pressure is given by the expression Cp,m = 97.78 + 0.0586(T - 280). Determine the standard molar entropy of N2H4(l) at 298.15 K.
