Question

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?

Answer 1

The total energy can be found by adding the different energies:
628 + 15,600 + 712
= 16.94 kJ
