10. The enthalpy of fusion for benzene (C6H6, 78.0 g/mol) is 127.40 kJ/kg, and its melting point is 5.5°C. What is the entropy change when 1 mole of benzene melts at 5.5°C?

Explanation:

Hello,

In this case, the entropy of fusion is computed in terms of the enthalpy of fusion considering the fusion temperature in kelvins:

Thus, since the enthalpy of fusion is given in kJ/kg we must compute the grams of benzene in mole of benzene via its molar mass:

Next:

Finally, the entropy:
