What is the formula for ammonium sulfide? Capitalization and punctuation count. How many hydrogen atoms are in 2.90 mol of ammonium sulfide?

Answer 1

Ammonium sulfide = (NH₄)₂S

1 mol (NH₄)₂S contains 8 moles of H atoms

2.90 mol (NH₄)₂S x 8 moles H atoms / mole (NH₄)₂S = 23.2 moles H atoms

Converting to number of H atoms ...

23.2 moles H atoms x 6.02x10²³ atoms / mole = 1.40x10²⁵ H atoms
