Atoms of which group in the periodic table have a valence shell electron configuration of ns2 np2? I tried 1 and 2 and it said they were wrong

A5 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?
