Chapter 6, Problem 147P(choose chapter or problem)
A 20.3-g sample of an unknown metal and a 28.5-g sample of copper, both at \(80.6^{\circ} \mathrm{C}\), are added to 100 g of water at \(11.2^{\circ} \mathrm{C}\) in a constant-pressure calorimeter of negligible heat capacity. If the final temperature of the metals and water is \(13.7^{\circ} \mathrm{C}\), determine the specific heat of the unknown metal.

QUESTION:
A 20.3-g sample of an unknown metal and a 28.5-g sample of copper, both at \(80.6^{\circ} \mathrm{C}\), are added to 100 g of water at \(11.2^{\circ} \mathrm{C}\) in a constant-pressure calorimeter of negligible heat capacity. If the final temperature of the metals and water is \(13.7^{\circ} \mathrm{C}\), determine the specific heat of the unknown metal.
ANSWER:Step 1 of 2
For this problem the heat released by the metals will be equal to the heat absorbed by the water.
