A 5 mole sample of liquid acetone is converted to a gas at 75. 0°C. If 628 J are required to raise the temperature of the liquid to the boiling point, 15. 600 kj are required to evaporate the liquid, and 712 J are required to raise the final temperature to 75. 0°C, what is the total energy required for the conversion?
