(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given

-Total Energy for [itex]Li \rightarrow Li ^{3+} = 1.960 * 10^{4} kJ/mol[/itex]

-First Ionization Energy of Li = [itex]5.20 * 10^{2} kJ/mol[/itex]

2. Relevant equations

Other than the equation in the image, I used the equation:

Etotal = E1 + E2 + E3

3. The attempt at a solution

Since Etotal and E1 are given, I have E2 and E3 left to solve.

To solve for E3, I used the equation in the picture.

Li^2+= A hydrogen atom (1 electron), I used the equation in the picture to solve for the energy for a single electron. Energy = -1.962*10^-17 J

The problem is, I don't know what to do with that number. How do I convert energy of a single electron to ionization energy?
