A student drops two metallic objects into a 120 g tin container holding 150 g of water at 77,0°F. One object is a 200 g cube of copper that is initially at 358 K, and the other is a chunk of aluminum that is initially at 41,0°F. The water reaches a final temperature of 31,5°C. What is the mass of the aluminum chunk?
