The heats of solution of one mole of Na and that of Na_2Oin water under standardconditions are -183.79 kJ/mol and -237.94 kJ/mol respectively, water being taken in large excess in both the cases. Calculate the standard heat of formation of sodium oxide if the standard heat of formation of water is –285.84 kJ/mol. |
