You can see each (NH4)2S has
2 N atoms
8 H atoms
1 S atom
So moles H atoms = 8 x moles (NH4)2S
= 52.0 moles H
1 mole anything = 6.022x10^23 units of that anything
So number H atoms = moles H atoms x 6.022x10^23 atoms/mol
= 52.0 x 6.022x10^23 atoms/mol
= 3.13x10^25 atoms of H

Answer : The number of hydrogen atoms are, [tex]134.89\times 10^{23}[/tex]
Explanation : Given,
Moles of hydrogen atoms = 2.80 mole
As we know that, the formula of ammonium sulfide is, [tex](NH_4)_2S[/tex]. In ammonium sulfide, there are 2 atoms of nitrogen, 8 atoms of hydrogen and 1 atom of sulfur.
Now we have to calculate the number of hydrogen atoms.
As, 1 mole of [tex](NH_4)_2S[/tex] contains [tex]8\times 6.022\times 10^{23}[/tex] number of hydrogen atoms.
So, 2.80 mole of [tex](NH_4)_2S[/tex] contains [tex]2.80\times 8\times \times 6.022\times 10^{23}=134.89\times 10^{23}[/tex] number of hydrogen atoms.
Therefore, the number of hydrogen atoms are, [tex]134.89\times 10^{23}[/tex]
