1.5 x 10¹⁴atoms per person

Explanation:

A mole of substance is the amount that contains the avogadro's number of particles.

  1 mole =  6.02 x 10²³atoms

Total population of the world is 4 billion = 4 x 10⁹people;

 Amount of atom each person gets is:

                      =

                       =

                        = 1.5 x 10¹⁴atoms per person
