How many hydrogen atoms are in 6.20 mol of ammonium sulfide?

First identify the molecular formula of ammonium sulphide to determine the number of hydrogen atoms present the molecule.

ammonium sulphide =

According to molecular formula, there are eight hydrogen atoms present in the molecule.

Thus, moles of hydrogen atom is calculated by the multiplication of number of hydrogen atoms and moles of ammonium sulphide.

Number of moles of hydrogen atom =

= 49.6 moles

Now, 1 mole of atom = Avogadro number ()

Number of hydrogen atoms =

=

=

= atoms of hydrogen

Hence, is the number of hydrogen atoms.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

the objects have the same charge.
