A piece of iran, which has a specific heat capacity of 0.452 J-g1. C, with a mass of 54.3218 g is heated in a water bath until it reaches a temperature of 98.2 C. The iron is then transferred into a coffee-cup calorimeter made of nested Styrofoam cups that contains 68.5314 g af water initially at 22.1 °C. The final temperature of the entire system is 27.5 °C. Based on this information, determine the calorimeter constant C for this particular calorimeter in J-C. Recall that the specific heat capacity of water is 4.184Jg.C.
