0.58 mоles оf а reаctiоn in аqueous solution are completed in a calorimeter. The mass of the solution (including the reaction components) is 175 g and the heat capacity of the solution is 4.18 J/(g*K). The temperature increases by 2.8 K. What is the reaction enthalpy? Answer in kJ/mol. Do not type units. Do not use scientific notation.
