Answer:
2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.
Explanation:
- The potassium sulfide has the chemical formula K₂S.
∴ Every 1.0 molecule of K₂S composed of 2.0 atom of K and 1.0 atoms of S.
So, 2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.
