I know that Formal concentration differs from Molar concentration, in that Formal concentration

indicates moles of the original chemical formula in solution, without regard for the species that actually exist in solution.

But for example, If I'm given the Molarity of Barium Chloride (BaCl2) to be 0.12M

What am i supposed to do to get the Formal concentration?

In this case aformal concnetration is equivalent to molar concentration of positive or negative charges in the solution, and
F= 2M

molar concentration of positive or negative charges in the solution

what does this mean
