First and second ionization energies of magnesium are $7.646$ and $\text{15}\text{.035}\text{eV}$ respectively. The amount of energy in $\text{kJ/mol}$ needed to convert all the atoms of Magnesium into ${\text{Mg}}^{\text{2+}}$ ions present in $\text{12}\text{mg}$ of magnesium vapours is: (Report your answer by multiplying with $\text{10}$ and round it upto nearest integer)
[Given: $\text{1}\text{eV}\text{=}\text{96}\text{.5}\text{kJ}{\text{mol}}^{- \text{1}}$]
