What is the specific heat of the metal?

A 250 g sample of metal shot is heated to a temperature of 90 degrees Celsius. It is placed in 100 g of water in a brass calorimeter cup with a brass stirrer. The total mass of the cup and the stirrer is 50 g. The initial temperature of the water, stirrer, and the calorimeter cup is 20 degrees Celsius. The final equilibrium temperature of the system is 30 degrees celsius. What is the specific heat of the metal sample. the specific heat of brass is 0.092 cal/g-C
