Question $3(1$ point$)$

Calculate the lattice enthalpy in $\{$:$k\frac{J}{m}ol)$ of the $M{F}_2$ metal fluoride using the

following data:

Bond dissociation enthalpy of $F_2(g)=159k\frac{J}{m}ol$

Electron affinity of $F=-328k\frac{J}{m}ol$

Enthalpy of sublimation of $M=109k\frac{J}{m}ol$

First ionization energy of $M=368k\frac{J}{m}ol$

Second ionization energy of $M=731k\frac{J}{m}ol$

Standard enthalpy of formation of $M{F}_2(s)=-307k\frac{J}{m}ol$

Refer to sections $9\mathrm{.}4$ and $9\mathrm{.}5$ in the textbook for definitions of ionization energy and

electron affinity. Do not use scientific notation for your answer. Do not enter units.
