Question #16f9b Chemistry Thermochemistry Calorimetry 1 Answer Manikandan S. Aug 16, 2017 Use heat balance & mass balance Explanation: The final volume of the mixture is #4l# assuming the density is constant. Then the heat balance is #V\cancel{\rhoC_p}T_f = V_1\cancel{\rhoC_p}T_1+V_2\cancel{\rhoC_p}T_2# #4T_f = 100+40*3# #T_f = 220/4# #T_f = 44^oC# Answer link Related questions How does differential scanning in calorimetry work?
