Calculate the amount of water (M.W. = 18.02 g/mol) at its boiling point that would be vaporized by 180 Calories (note the capital C). The heat of fusion for water at its boiling point is 40.7 kJ/mol, and 1 calorie = 4.184 J.

moles of water=(180 calories*4.184 J/calories) / (40700J/mol)=0.0185mol
mass of water=0.0185mol*18g/mol=0.333g
