Answer is: entropy of evaporization of benzene is 86,7 J/mol·K.
T(benzene - C₆H₆) = 80,1 °C = 80,1 + 273,15 = 353,25 K.
ΔHvap(C₆H₆) = 30,7 kJ/mol.
ΔSvap(C₆H₆) = ?
ΔS(C₆H₆) = ΔH ÷ T
ΔS(C₆H₆) = 30,7 kJ/mol ÷ 353,25 K
ΔS(C₆H₆) = 0,087 kJ/mol·K = 86,7 J/mol·K.

Answer:
1:put these in sneaker and add water since sulphur is insoluble and the sugar will dissolve and the sand will settle obtain the sulphur
2:filter the mixture of sand and sugar solution to obtain the sand as residue and solution as filtrate
3:using an evaporating dish evaporate sugar solution to saturation not dryness to get crystals.
