What is the energy change (in kJ) when 0.487 kilograms of diethyl ether (C4H10O) is condensed from a gas at 34.6°C (its boiling point) to a liquid at the same temperature? The ΔHvaporization for diethyl ether = 26.0 kJ/mol.
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?
