A 35.41-g sample of Cu(s) at 96.73°C was added to a constant-pressure calorimeter containing 148.3 g of H2O(l) at 25.20°C. The final temperature of the system was 26.66°C. Assuming no heat loss to the surroundings, what is the calorimeter constant? C(Cu) = 24.435 J/mol.K; C(H2O) = 75.291J.K-1.mol-1
