Question: A student drops two metallic objects into a 1 2 0 - g stainless steel ( c = 0 . 1 0 8 c a

A student drops two metallic objects into a 120-g stainless steel (c=0.108calgm.C) calorimeter holding 150 g of water at 25C. One object is a 200-gCu initially at 85C, and other is Al initially at 5C. They also simultaneously drops 15 g of ice at -5C. The final equilibrium temp reaches to 20C. What is the mass of Al?
