5. When 1.00L of a 1.00 M Ba(NO3)2 solution at 25.0oC is mixed with 1.00 L of a 1.00 M Na2SO4 solution at 25.0oC in a calorimeter, the white solid, BaSO4 forms and the temperature of the mixture increases to 28.1oC. Assuming that the calorimeter absorbs only a negligible quantity of heat, that the specific heat capacity of the solution is 4.18 J/oC g and that the density of the final solution is 1.0 g/mL, calculate the enthalpy change per mole of BaSO4 formed.
