1. The problem statement, all variables and given/known data An aluminum cup contains 217g of water at 21.2oC. A 404g sample of silver at an initial temperature of 80.8oC is placed in the water. A 41.0g copper stirrer is used to stir the mixture until it reaches its final equilibrium temperature of 25.7oC. Calculate the mass of the aluminum cup. 2. Relevant equations Q=mCdeltaT heat lost=heat gained 3. The attempt at a solution Could someone please help me set the problem up w/o numbers. Thanks.
