Hello!
To find the number of moles in a sample of 4.57 x 10^24 atoms, we need to use Avogadro's number, which is 1 mole = 6.02 x 10^23.
To find how many moles, we divide the given sample by Avogadro's number.
(4.57 x 10^24) / (6.02 x 10^23) ≈ 7.59136
Using the amount of significant figures given (3), the answer is 7.59 moles of neon (Ne).
