The chemical formula of sodium sulfide is Na2S.
Sodium sulfide or Disodium sulfide. Both are correct terms for that formula.
The name for the compound with the formula Na2S is sodium sulfide.
It is a Ionic bond between Sodium Ions and Sulfide Ions. The formula name is Sodium Sulfide.Na = sodiumS = sulfurSodium Sulfide?
No. Sodium sulfate has the formula Na2SO4, but sodium sulfide has the formula Na2S and substantially different chemical properties from those of sodium sulfate.
The formula of sodium sulfide is Na2S, where the 2 should be a subscript. It means that in the ionic compound there are 2 moles of sodium ions for every 1 mole of sulfide ions.

I suppose that you think to Na2S - sodium sulfide.
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
The equation for the reaction specified is 2 NaOH + H2S -> Na2S + H2O. Therefore, if the yield were 100 %, two formula masses of sodium hydroxide are required to produce one formula mass of sodium sulfide. The gram formula mass of NaOH is 40.00 and that of sodium sulfide is 78.04. The specified number of grams of sodium hydroxide corresponds to 2.53/40.00 or 0.06325 formula masses and therefore would provide half this many formula masses of sodium sulfide, for a mass of (0.06325)(78.04)/2.000 or 2.568 grams of sodium sulfide. Since the yield is specified as 91.0 %, the actual amount of sodium sulfide produced is 2.25 grams, to the justified number of significant digits.
