A piece of titanium metal with a mass of 21.6 g is heated in boiling water to 99.5 °C and then dropped into a coffee-cup calorimeter containing 75.0 g of water at 21.8 °C. When thermal equilibrium is reached, the final temperature is 24.5 °C. Calculate the specific heat capacity of titanium. (The specific heat capacity of liquid water is 4.184 J/g. K.) Specific heat capacity= J/g. K

Consider an unknown metal X with a mass of 67.5 g at an initial temperature of 76.1 °C. The metal is placed in 88.7 g of water initially at 20.5 °C in an insulated container. The final equilibrium temperature of the system is 32.1 °C. Calculate the specific heat (J/(g·°C)) of the metal X.   Use Cs = 4.18 J/(g·°C) for the specific heat of water. Assume that the only energy exchange that occurs is between the metal and the water.
