A 36.0 g piece of copper metal is initially at 100.0°C. It is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperature of 20.0°C. After stirring, the final temperature of both copper and water is 25.0°C. Assuming no heat losses, and that the specific heat (capacity) of water is 4.18 J/(g-°C), what is the specific heat capacity of the copper in J/(g°C)? Express your answer in decimal notation rounded to three significant figures.
