A piece of copper of mass m = 90 g at a temperature t1 = 90 C

Question:

A piece of copper of mass m = 90 g at a temperature t1 = 90 °C was placed in a calorimeter in which ice of mass 50 g was at a temperature – 3 °C. Find the entropy increment of the piece of copper by the moment the thermal equilibrium is reached.
