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

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
