Answer to Question #148077 in General Chemistry for Erick

Question

What is the final temperature of the water if 35.1 kJ of energy are added to 100.0 g of ice at -4.5°C?

Answer 1

Quantity of Heat= m_ic_i(T_fi-T_ii) + mL_f + m_wc_w(T_fw-T_iw)

                    35.1= 0.1×2.04× (0- -4.5) + 0.1×335 +0.1×4.184(T_fw-0)

                       35.1= 0.918 + 33.5 +0.4184 T_fw

           35.1-34.418= 0.4184 T_fw

             0.682/0.4184= T_fw

             T_fw= 1.63 °C
