What is Qcal?
Chemistry
Assume a piece of hot metal is added to a calorimeter containing 50mL of water at 22C. The amount of heat released by the metal was determined to be 1000J, and the equilibrium temperature in the calorimeter was 26C. Remembering that the specific heat of water is 4.18 J/gC, how...

Calculate the calorimeter constant if 25g of water at 50C was added to 25g of water at 25C with a resulting temperature of 35C? The answer is 52.3 but I do not know how to get to this. I hope someone can help. Thanks!

Chemistry
Assume the heat absorbed by the calorimeter was 200J. What is the calorimeter constant (Heat Capacity) if the temperature changed from 22C to 26C? I know the answer is 50 J/k. But I am not sure how to get this.
