Question

Calculate the standard enthalpy of formation of the M¿O(s) metal oxide (OHf in kJ/mol) using the following data:
Bond dissociation enthalpy of O2(g) = +498 kJ/mol
First electron affinity of o = -141 kJ/moI
Second electron affinity of o = +744 kJ/mol
Enthalpy of sublimation ofM = + 119 kJ/moI
First ionization energy of M = + 408 kJ/mol
Lattice enthalpy of M2O(s) = -2231 kJ/mol
