25. 000 grams of water at 45. 00oc was added to 25. 00 grams of water at 20. 30oc in a coffee cup calorimeter. Upon mixing, the equilibrium temperature attained by the system was 31. 40oc. The specific heat of water is 4. 184 j/goc. What is the calorimeter constant ccal in j/oc for the coffee cup calorimeter?.
