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?
2. What is the change in entropy in the system when 4.50g of ethanol (CH3CH2OH) condenses to liquid at its normal boiling point of 78°C? The heat of vaporization for ethanol is 38.56kJ/mol.
