ΔS = entropy, J/mol•K
ΔH = enthalpy, J
T = temperature, K
ΔHvap of acetone = 31.3 kJ/mol → convert from kJ to J: 1 kJ = 103 J

Tb = 56.1°C + 273.15 = 329.25 K
Calculate the change in entropy that occurs in the system when 30.5 g of acetone (C3H6O) vaporizes from a liquid to a gas at its normal boiling point (56.1 ˚C).
