Zinc is used to form a corrosion inhibiting surface on galvanized steel. Determine the number of Zn atoms in 2.50 mol of Zn

The number of Zn atoms in 2.50 moles of Zn is equal to atoms.

To calculate the number of atoms present in a given amount of moles, it is necessary to use Avogadro's constant:

                                 1 mole =   atoms

So, in 1 mole of a substance we have atoms, having said that we can do the following calculation:

                                      atoms of Zn

In this way, the number of Zn atoms in 2.50 moles of Zn is equal to atoms.

1.505x10^24 atoms

Explanation:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 atoms.

From the above hypothesis, it became clear that 1 mole of Zn also contains 6.02x10^23 atoms.

Now, if 1 mole of Zn contains 6.02x10^23 atoms,

then 2.5 moles of Zn will contain = 2.5 x 6.02x10^23 = 1.505x10^24 atoms

Therefore, 2.5 moles of Zn contains 1.505x10^24 atoms
