An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10.0°C. Two metallic blocks are placed into the water. One is a 50.0-g piece of copper at 80.0°C. The other has a mass of 70.0 g and is originally at a temperature of 100°C. The entire system stabilizes at a final temperature of 20.0°C. (a) Determine the specific heat of the unknown sample?

Question
An aluminum calorimeter with a mass of 100 g contains 250 g of water.
The calorimeter and water are in thermal equilibrium at 10.0°C. Two metallic blocks are placed
into the water. One is a 50.0-g piece of copper at 80.0°C. The other has a mass of 70.0 g and is
originally at a temperature of 100°C. The entire system stabilizes at a final temperature of
20.0°C. (a) Determine the specific heat of the unknown sample?
