A metal container, which has a mass of 7,2 kg contains 17.2 kg of water. A 3.3-kg piece of the same metal, initially at a temperature of 180.0°C, is dropped into the water. The container and the water initially have a temperature of 16.5ºC and the final temperature of the entire system is 18.5°C. Calculate the specific heat of the metal. Note: Units for specific heat is J/(kg*K). You do not need to enter the units.
