A Piece of Copper Metal Is Initially at 100 $\degree$ C It Is Dropped into a Coffee Cup Calorimeter Containing

A piece of copper metal is initially at 100.0 $\degree$ C. It is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperature of 20.0 $\degree$ C. After stirring, the final temperature of both copper and water is 25.0 $\degree$ C. Assuming no heat losses, and that the specific heat (capacity) of water is 4.18 J/(g ? K) , what is the heat capacity of the copper in J/K?

A) 2.79 J/K
B) 3.33 J/K
C) 13.9 J/K
D) 209 J/K
E) None of these choices is correct.
