At 25°C, the standard enthalpy of formation of anhydrous sodium carbonate is –1130.9 kJ/mol, whereas the standard enthalpy of formation of sodium carbonate monohydrate is –1430.1 kJ/mol.  Determine ΔH° at 25°C for the reaction
         Na2CO3(s) + H2O(l) → Na2CO3·H2O(s).
(Given:  ΔH°f[H2O(l)] = –285.8 kJ/mol)
◦ –585.0 kJ/mol
◦ –299.2 kJ/mol
◦ –285.8 kJ/mol
◦ –156.3 kJ/mol
◦ –13.4 kJ/mol
