1. Avogadro's Number:

* Avogadro's number tells us the number of atoms or molecules in one mole of a substance. It's approximately 6.022 x 10^23.

2. Calculation:

* Divide the number of atoms by Avogadro's number:

(5.7510 x 10^24 atoms Al) / (6.022 x 10^23 atoms/mol) ≈ 9.55 moles Al

Therefore, 5.7510 x 10^24 atoms of aluminum are equivalent to approximately 9.55 moles of aluminum.
