How many atoms of zinc are in 6.05 moles of zinc

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

Yes it would be a physical change.
