The molar heats of fusion and vaporization of a certain substance are 2.26 kJ/mol and 8.16 kJ/mol, and its melting point and boiling point are −184°C and −108°C, respectively. Calculate the entropy changes for fusion (solid to liquid) and vaporization (liquid to gas). ΔSfus = J/K·mol ΔSvap = J/K·mol
