</h2>
Explanation:
<u>First of all cross multiply</u>
That's
<u>Next divide both sides by </u>

We have
We have the final answer as
Hope this helps you
A)
First ionization energy of Li:
Li(g) + 520 kJ/mol → Li⁺(g) + e⁻
B)
Electron affinity of Fluorine:
F(g) + e⁻ → F⁻(g) + 328 kJ/mol
NA = 6.022*10^23
number of atoms = number of moles * avogadros number
number of atoms = <span>6.022*10^23 * 1.4 moles * 4 atoms / molecules of PCl3
Number of atoms = 3.37*10^23 atoms.</span>
