What is the formula for ammonium sulfide? Capitalization and punctuation count. How many hydrogen atoms are in 3.00 mol of ammonium sulfide?

Answer 1

Ammonium = NH₄⁺

Sulfide = S^2-

So it will take 2 NH₄⁺ ions for each S^2- ion. Thus, the formula is (NH₄)₂S

How many hydrogen atoms are in 3.00 mol of (NH₄)₂S?

Each mol of (NH₄)₂S contains 8 mols of hydrogen atoms

3.00 mol (NH₄)₂S x 8 mol H atoms / mol (NH₄)₂S = 24 mols of H atoms

24 mols H atoms x 6.022x10²³ atoms / mol = 1.45x10²⁵ H atoms
