Answer: The mass in
atoms of zinc is 0.405 g.
Explanation:
Given: Atoms of zinc = 
It is known that 1 mole of every substance contains
atoms. So, the number of moles in given number of atoms is as follows.

As moles is the mass of a substance divided by its molar mass. So, mass of zinc (molar mass = 65.39 g/mol) is calculated as follows.

Thus, we can conclude that the mass in
atoms of zinc is 0.405 g.
