This question asks: Calculate the change in entropy that occurs in the system when 1.00 mol of methanol (CH3OH) vaporizes from a liquid to a gas at its boiling point (64.6 degrees Celcius). For methanol, enthalpy of vaporization = 35.21 kJ/mol I'm getting the correct answer (104) but I'm getting a negative for some reason, and the book says it's positive, but the formula changeinEntropy = -enthalpy of system/T, so why isn't this number negative?
Calculate the change in entropy that occurs in the system when 3.20 mol of acetone (C3H6O) melts at its melting point (−− 94.8 ∘C). ΔH∘fus=5.69kJ/mol Express your answer in joules per kelvin to three significant figures.
