1. A 25.0 gram piece of metal is heated to 98.0C. The metal is then placed into calorimeter containing 85.0mL of water at 35celsius. The temperature of the calorimeter when the metal is added goes up to 77celsius. What is the specific heat of the metal?
2. Determine the molarity of Fe+3 ions and SO4-2 ions in a solution prepared by dissolving 48.05g of Fe2(SO4)3 in enough water to make 800.0mL of solution.
