An irregular lump of an unknown metal has a measured density of 5.26 g/mL. The metal is heated to a temperature of 183 °C and placed in a graduated cylinder filled with 25.0 mL of water at 25.0 °C. After the system has reached thermal equilibrium, the volume in the cylinder is read at 33.8 mL, and the temperature is recorded as 43.0 °C. What is the specific heat of the unknown metal sample? Assume no heat is lost to the surroundings. C = J g. °C
