2-Propanol (isopropanol) is commonly used as 'rubbing alcohol' to relieve sprain injuries in sport: its action is due to the cooling effect that accompanies its rapid evaporation when applied to the skin. In an experiment to determine the enthalpy of vaporization of 2-propanol, a sample was brought to the boil. It was then found that when an electric current of 0.812 A from a 11.5 V supply was passed for 303 s, then 3.5 g of the alcohol was vaporized. What is the (molar) enthalpy of vaporization of isopropanol at its boiling point? kJ/mol. 3 sig. number normal format.
