A block of 55.40 g of gold at 100.0oC is added to 150.0 g of water at 25.0oC in a coffee cup calorimeter.  After 10 minutes, the temperature of water comes to a constant. What’s the final temperature of the water inside the coffee cup calorimeter? Assume the coffee cup calorimeter is a perfect insulator without ant gain/loss of heat.  Specific heat capacity of water is 4.184 J/(g oC).  Specific heat capacity for gold is 0.129 J/(g oC). Mark your answer next to words “Final answer is”. You must follow significant figure rules.  Show your work here to receive full credit.
