A student followed the procedure in the lab manual to determine the heat capacity of the calorimeter. The student measuredthe temperature of 49.2 mL of room temperature water to be 20.9 °C and that of 49.4 mL of cold water as 1.8 °C. Aftercombining the two water samples in the calorimeter the student acquired temperature as a function of time data. A plot ofthese data was constructed, an extrapolation to time zero was made, and the final temperature was determined to be 12.7 °C.What is the heat capacity of the calorimeter (Ccal) in units of J/°C? (Enter your answer as a number without units.)

Let's break down into the steps for finding the heat capacity of the calorimeter:1. Calculate heat…
