In a calorimetry experiment, an unknown metal with a mass of 27.4 g that has been in heated to a temperature of 94.0 °C is placed in a coffee cup calorimeter containing 79.8
g of water initially at a temperature of 22.6 °C. After the water and metal have reached
thermal equilibrium, the final temperature reading of the calorimeter is 28.7 °C.
Calculate the specific heat of the unknown metal in J/gºC.
