A 50-G Cube of Ice, Initially at 0 $\degree$ C, Is Dropped into 200 G of Water in an Is

A 50-g cube of ice, initially at 0.0 $\degree$ C, is dropped into 200 g of water in an 80-g aluminum container, both initially at 40 $\degree$ C. What is the final equilibrium temperature? (Specific heat for aluminum is 900 J/kg· $\degree$ C, the specific heat of water is 4186 J/kg· $\degree$ C, and L_f = 3.33 * 10⁵ J/kg.)

A) 17.6 $\degree$ C
B) 9.5 $\degree$ C
C) 12.1 $\degree$ C
D) 20.6 $\degree$ C
