For each trial, enter the amount of heat gained by the chemical system of ammonium nitrate, qrxn. The specific heat of water is 4.184 J/goC. Report your answer using 4 digits.

The information given is:
Trial # Tiwater Tf Masswater
#1: 21.2 10.8 24.990
#2: 20.8 9.50 25.000
#3: 20.9 9.20 25.010

The equation needed is qrxn = -(qwater+qcalorimeter) I found the qwater, but I need help finding the qcalorimeter so I can determine the qrxn. Please help!
