In the solution manual, it shows that but I don't understand why the term is in the numerator and why is in the denominator.

Hey Netpheel,

Keep in mind that Na2CO2 would dissociate into its individual ions in an aqueous solution.
That specific equivalence in the dimension factor is meant to demonstrate that for every mole of Na2CO2, there are 2 moles of Na+ ions. You can figure this out by looking at the subscript on the Sodium (Na), which shows that every molecule of Sodium Carbonite requires requires 2 Na+ ions to form.

Much Joy,
Atul
