Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5ļ°c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/gādegree c). calculate the calorimeter constant. (smĪ“t)warm water = -[(smĪ“t)cold water + (calorimeterĪ“tcold water)]
