4. A solution calorimeter was filled with 500 cm3 of 2M Na2SO4 at 25C and reacted with 100cm3 of 10M Ba (NO3)2 solution in a glass ampoule placed in the solution by breaking the ampoule. The temperature of the calorimeter and its content rose to 35.33 C and BaSO4 collapsed. Since the heat absorbed by the calorimeter vessel is negligible, find the standard reaction enthalpy by taking the density of the reaction solution 1g cm-3 and the heating temperature 4.18 Jg- 1 K-1
