A chunk of iron at 90.6°C was added to 200.0 g of water at 15.5°C in a coffee cup calorimeter.
Assume that no heat was exchanged with the surroundings. The specific heat of iron is 0.449 J/g°C, and the specific heat of water is 4.18 J/g°C. The temperature of the mixture stabilized at 18.2°C. a) Calculate the heat absorbed by the water
b) Calculate the heat released by the chunk of iron.
c) Calculate the mass of iron added.
