For ethyl alcohol, C2H5OH, the enthalpy of fusion is 108.9 J/g, and the entropy of fusion is 31.6 J/mol •K. The enthalpy of vaporization at the boiling point is 837 J/g, and the molar entropy of vaporization is 109.9 J/mol •K.

Explanation:

Hello,

In this case, given the enthalpies and entropies of boh fusion and boiling, we can compute both the fusion and boiling points as shown below, considering ethanol's molar mass is 46 g/mol:

Best regards.
