To determine the calorimeter constant (Ccal) of a nested "coffee cup" calorimeter, a student pours 50.0 g of water at 24.34°C into the calorimeter. She then quickly adds 50.0 g of hot
water at 76.06°C and replaces the calorimeter lid. She finds that the water has a final
temperature of 49.06°C. What is the value of the calorimeter constant? The specific heat for
J
water is 4.184
