Respuesta :
(NH4)2S this is chemcial formula of ammonium sulfide
in 1 mole of ammonium sulfide there are 4*2 = 8 moles of H atoms are present
but in 0.69 moles of ammonium sulfide = 8 * 0.69 = calculate it
Answer : The number of atoms of hydrogen are [tex]3.32\times 10^{25}[/tex]
Explanation : Given,
Moles of ammonium sulfide = 6.90 moles
The chemical 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.
As we know that,
1 mole of substance always contains [tex]6.022\times 10^{23}[/tex] number of atoms.
As, 1 mole of ammonium sulfide contains [tex]8\times 6.022\times 10^{23}[/tex] number of hydrogen atoms
So, 6.90 mole of ammonium sulfide contains [tex]6.90\times 8\times 6.022\times 10^{23}=3.32\times 10^{25}[/tex] number of hydrogen atoms.
Therefore, the number of atoms of hydrogen are [tex]3.32\times 10^{25}[/tex]
