I THINK it goes like THIS....
([Na+]g/mol/NaSO4g/mol) x 36.6mg NaSO4 = Concentration of [Na+]

Usually the [X] indicates the concentration in molarity (Moles solute/ L solution). From the given data, you can use the molecular weight of NaSO4 to find its molarity. This gives the following expression:
* The formula should be Na2SO4 (like H2SO4). Going on this assumption...
(X moles Na2SO4/ L sol'n) * (2 mole Na+ / 1 mole NaSO4) =
2X moles Na+ / L sol'n
This can be said because the sodium salt would ionize to give Na(+) and SO4(-2)
If the problem wants the concentration in grams, just convert using the molecular weight of sodium.
