A sample of Na2SO4 (s) is dissolved in 225g of water at 298 K such that the solution is 0.25 M in Na2SO4. A temperature rise of 0.112 degrees Celsius is observed. the calorimeter constant is 330.0 J/K. Calculate the enthalpy of solution of Na2SO4 in water at this concentration. Compare your result with that calculated using data tables.
