Two 20.0g-ice cubes at -12.0 C are placed into 235 g of water at 25.0 C. Assuming no energy is transferred to or from the surroundings, calculate the final temperature of the water after all the ice melts.
heat capacity of H2O (s) 37.7 J/(mol K)
heat capacity of H2O (l) 75.3 J/(mol K)
enthalpy of fusion of H2O 6.01 kJ/mol
