A 75.00-g sample of an unknown metal is heated to 52.00°C. It is then placed in a coffee cup calorimeter filled with water. The calorimeter and the water inside have a combined mass of 225.0 g and an overall specific heat of 2.045 J/(gi°C). The initial temperature of the calorimeter is 7.50°C. If the system reaches a final temperature of 9.08°C when the metal is added, what is the specific heat of the unknown metal?

The idea is that all the coffee cup calorimeter is insulated, therefore all of the energy that leaves the metal goes into the water.
qwater=-qmetal
