Five cubic meters of a 1.00-molar aqueous sulfuric acid solution (SG = 1:064) is stored at 25°C. Use data in Tables B.1 and B.11 to calculate the standard heat of formation of the solution in kJ/mol H₂SO₄ relative to the solute elements and water, and the total enthalpy of the solution relative to the same reference conditions.
