Question

A chunk of metal having a mass of 49.7g was warmed to 95.5°C and then dropped into a calorimeter
containing 45.3g of water initially at 22.1°C. The final temperature of the water/metal/calorimeter was
28.0°C. Assuming that the calorimeter has a heat capacity of 20. J/°C and that water has a specific heat
of 4.18 J/g °C, what is the specific heat of the metal? 

Expert Solution
Step 1

Mass of metal = 49.7g 

Mass of water = 45.3g

Heat capacity for water = 4.18J/g°C

Final temperature = 28°C

Heat capacity of calorimeter = 20J/°C
