How much energy in kJ will be required to convert all the magnesium atoms into magnesium ions present in 12 mg of the metal vapours? , for Mg being 7.646 and 15.035 eV respectively.

How much energy in kJ will be required to convert all the magnesium at

1.	How much energy in kJ will be required to convert all the magnesium atoms into magnesium ions present in 12 mg of the metal vapours? , for Mg being 7.646 and 15.035 eV respectively.
Answer» that, First and SECOND ionization energies of Mg are and (GIVEN). Therefore, the TOTAL energy REQUIRED to convert magnesium atoms to magnesium ions is =22⋅681eV Total required energy in TERMS of kJ is 22⋅68×96⋅49=2188⋅39 kJ Now, molar mass of magnesium is 24 gm/mol means 24 X 103 mg/mol So, 12 mg of magnesium = Therefore, total energy required to convert all Mg atoms to ions is
