A 58.95 g sample of an unknown metal is heated to an initial temperature of 85.60 ˚C. It is placed in a calorimeter that has a heat capacity of 36.2 J/˚C and contains 120.0 g of water at an initial temperature of 20.42 ˚C. After the metal is placed in the calorimeter, both the water and the metal reach a final temperature of 23.70 ˚C.
Determine the heat capacity of the unknown metal (cmetal).
