How many total atoms are in 3(NH4)2S

33atoms

Explanation:

An atom is the smallest particle that can take part in a chemical reaction.

The given compound is:

                3(NH₄)₂S

Here we have 3 moles of (NH₄)₂S ;

 So:

   Total number of atoms:

            2 atoms of N

           2 x 4 atoms of H

              1 atom of S

Total  = 2 + 8 + 1  = 11 atoms

 So;

    The total atom  = 3 x 11 = 33atoms

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
