Please HELP! Chewbacca finds an unknown piece he believes is part of C3PO of metal weighing 91.5 g. To test this it is heated to 93.7βC, it is dropped into 284.1 g of water at 25.2βC. When Equilibrium is reached, the temperature of the water and piece of metal is 28.9βC. Determine the specific heat of the metal(in cal/gβC). Assume the heat capacity of the container, a Styrofoam cup, is negligible. Hint: heat gained by water = heat lost by metal.
