a 13-g sample of an unkown metal is heated to 96.0 degrees C. The metal is then placed into a 27.0-g aluminum caloorimeter cup ( with c = 900 J/kg*degrees C) containing 180-g of water at 18.0 degrees C. When equilibrium is reached, the final temperature is 29.2 degrees C. What is the specific heat of the unknown metal?
