What you need is the heat of evaporation at 298 K . If the only figure you have is for 373 K, you can adjust for the temperature difference using conservation of energy : It should take the same energy to evaporate the water at 298 K and then heat the vapor to 373 K as it should to heat the water to 373 K and evaporate it there.
