A 42.1 g piece of metal was heated up to 97.4 oC and then dropped into a beaker containing 63.0 g of water at 22.0 oC. When the water and metal come to thermal equilibrium, the temperature is 30.10 oC. What is the specific heat capacity of the metal? Specific heat capacity of the water is 4.184 J/(g• oC)

The dimensions of a 1.50 X 102 g metallic block are 1.166 cm wide, 9.23 mm high, and 18.87 cm long. What is the density of the metallic block in g/cm3?
