Question 10 A sample of liquid butanol, C4H7OH, was brought to the boil in an open calorimeter. An electric current of 289 mA from a 12.0 V source was then passed through a resistive heater coil which was immersed in the liquid. The current was allowed to ow for a period of 245 5, during which time the temperature remained constant and 1.416 g of butanol was found to have evaporated. Calculate the molar enthalpy of vaporization of butanol. Express your answer in units of kJ/mol and with one decimal. Note that the molar mass of butanol is 72.12 g/mol
