A copper calorimeter can with mass 0.100 kg contains 0.160 kg of water and 1.80×10−2 kg of ice in thermal equilibrium at atmospheric pressure.

Question:
If 0.750 kg of lead at a temperature of 255degrees Celsius is dropped into the can, what is the final temperature of the system if no heat is lost to the surroundings?


i tried to set the heat of the iron equal to the heat of the entire calorimeter but its not working out
