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 23.5ο°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/gβdegree c). calculate the calorimeter constant. (smΞ΄t)warm water = -[(smΞ΄t)cold water + (calorimeterΞ΄tcold water)]
