How many hydrogen atoms are in 6.90 mol of ammonium sulfide?

(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

Explanation : Given,

Moles of ammonium sulfide = 6.90 moles

The chemical formula of ammonium sulfide is,

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 number of atoms.

As, 1 mole of ammonium sulfide contains number of hydrogen atoms

So, 6.90 mole of ammonium sulfide contains number of hydrogen atoms.

Therefore, the number of atoms of hydrogen are
