An aluminum cup contains 225 g of water and a 40-g copper stirrer, all at 27°C. A 424-g sample of silver at an initial temperature of 90°C is placed in the water. The stirrer is used to stir the mixture gently until it reaches its final equilibrium temperature of 32°C. Calculate the mass of the aluminum cup.
