Round your answer to two decimal places. A 78.51 g plate of an unknown metal is removed from boiling water (1.00x102 °C) and is immediately immersed in a calorimeter containing 62.87 g of water that is initially at 24.39°C. The final temperature is 28.89°C. It will be determined from your Excel graph. A 25.39 g sample of metal is heated to 98.6°C in a hot water bath until thermal equilibrium is reached. The metal is quickly transferred to 50.0 mL (50.0 g) of water at 22.2°C contained in a calorimeter. The thermal equilibrium temperature of the metal sample plus water mixture is 28.3°C.
