Answer:
2.09 mols of Neon
Explanation:
To convert from atoms to moles, you'd need to divide a value of a number of atoms by Avogadro's Constant, 6.023x10^23.
(1.26x10^24)/(6,023x10^23)=2.09198.
Significant figures is something you may or may not know, but you go with the lesser amount of sig figs (values), which gives us 2.09 moles.
