How many moles of each element are in one mole of (NH4) 2S?

1 mole of nitrogen, 8 moles of hydrogen, 1 mole of sulfur

1 mole of nitrogen, 6 moles of hydrogen, 1 mole of sulfur

2 moles of nitrogen, 6 moles of hydrogen, 1 mole of sulfur

2 moles of nitrogen, 8 moles of hydrogen, 1 mole of sulfur

2 moles of nitrogen, 8 moles of hydrogen, 1 mole of sulfur.

Explanation:

The ammonium sulfide (NH₄) ₂S salt contains: Sulfide anion carries charge of (-2) S⁻². Ammonium group cation carries charge of (-2) NH₄⁺. From the stichiometry of the compound ammonium sulfide (NH₄) ₂S: each sulfide anion (S⁻²) combines with 2 ammonium groups (NH₄⁺). If 1.0 mole of (NH₄) ₂S dissociated to its atoms, it will give 2.0 moles of nitrogen, 8.0 moles of hydrogen, and 1.0 mole of sulfur.

(NH₄) ₂S → 2N + 8H + S

So, 1.0 mole of (NH₄) ₂S contains 2.0 moles of nitrogen, 8.0 moles of hydrogen, and 1.0 mole of sulfur.
