A 30.5 g sample of an alloy at 90.5�C is placed into 49.1 g water at 24.5�C in an insulated coffee cup.?

A 30.5 g sample of an alloy at 90.5�C is placed into 49.1 g water at 24.5�C in an insulated coffee cup. The heat capacity of the coffee cup (without the water) is 9.2 J/K. If the final temperature of the system is 31.1�C, what is the specific heat capacity of the alloy? (c of water is 4.184 J/g�K)
