A piece of solid cadmium weighing 37.6 g at a temperature of 311 °C is placed in 376 g of liquid cadmium at a temperature of 370 °C. After a while, the solid melts and a completely liquid sample remains. Calculate the temperature after thermal equilibrium is reached, assuming no heat loss to the surroundings.

The enthalpy of fusion of solid cadmium is ΔHfus = 6.11 kJ/mol at its melting point of 321 °C, and the molar heat capacities for solid and liquid cadmium are Csolid = 25.9 J/mol K and Cliquid = 29.7 J/mol K.
