As we know that one mole contains 6.022 × 10²³ particles. And the number of particles are related to moles as,
# of Particles = Moles × 6.022 × 10²³ particles
In case of Zinc atoms,
# of Atoms = Moles × 6.022 × 10²³ Atoms/mol
Putting value of moles.
# of Atoms = 6.05 mol × 6.022 × 10²³ Atoms/mol
# of Atoms = 3.64 × 10²⁴ Atoms
