In a calorimetry experiment in the lab, you were able to record the following data:

Mass of water in a calorimeter = 90.0 g
Initial temperature of water in calorimeter = 22.0o C
Mass of unknown metal = 45.0 g
Initial temperature of hot metal = 100.0o C
Final temperature of water after you place hot metal in calorimeter filled with water = 28.0o C
Based on the above data, what is the Cp of the metal?
(Cp H2O = 4.184 J/g oC)
