A 40 g block of ice is cooled to -65°C. It is added to 569 g of water in an 69 g copper calorimeter at a temperature of 28°C. Find the final temperature. The specific heat of copper is 387 J/kg °C and of ice is 2090 J/kg °C. The latent heat of fusion of water is 3.33 x 105 J/kg and its specific heat is 4186 J/kg °C. Answer in units of °C.
