Suppose if the enthalpy of combustion for ethane = -2834 kJ, explain how much ethane, in grams, must be burned in order to heat 217.3 grams of water from 51°C to the boiling point as well as then boil all of it into the gas phase at 100°C. Define the enthalpy of vaporization of water = 40.8 kJ/mol as well as the specific heat of liquid water = 4.184 J/gK.
