If this energy were used to vaporize water at 100 ∘c, how much water in liters could be vaporized? assume that the density of water is 1.0 g/ml. the heat of vaporization of water at 100 ∘c is 40.7 kj/mol. (hint: begin by using the enthalpy of vaporization of water to convert between the given number of kilojoules and moles of water.)
