At 25°C, the Standard Enthalpy of Formation of Anhydrous Sodium $\Delta$

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 $\Delta$ H° at 25°C for the reaction Na₂CO₃(s) + H₂O(l) $\rarr$ Na₂CO₃·H₂O(s) .
(Given: $\Delta$ H°_f[H₂O(l) ] = -285.8 kJ/mol)

A) -585.0 kJ/mol
B) -299.2 kJ/mol
C) -285.8 kJ/mol
D) -156.3 kJ/mol
E) -13.4 kJ/mol
