A copper calorimeter can with mass 0.169 kilogram contains 0.201 kilogram of water and 2.90×10-2 kilogram of ice in thermal equilibrium at atmospheric pressure. The relevant latent heats and specific heats can be found in your book. If 0.832 kilogram of lead at a temperature of 383 is dropped into the can, estimate what is the final temperature of the system if no heat is lost to the surroundings?
