Problem- The standard entropy of vaporization of acetone is approximately 85 J/K mol at its boiling point. (a) Estimate the standard enthalpy of vaporization af acetone at its normal boiling point of 56.2 degrees C. (b) What is the entropy change of the surroundings when 10. g of acetone, CH3COCH3, condenses at its normal boiling point?
