The specific heat of copper is 0.385 J/gºC. A 95.0 g block of copper is heated to 77.9°C and placed into a calorimeter that contains 42.0 mL of water at 20.4 degrees * C . Assuming no heat loss, what will be the final temperature of the copper and water?

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?
