Answer:
423.44 moles
Explanation:
We need to find no of moles in [tex]2.55\times 10^{26}\ \text{atoms}[/tex] of Neon.
We know that,
[tex]1\ \text{mol of atoms}=6.022\times 10^{23}\ \text{atoms}[/tex]
[tex]2.55\times 10^{26}\ \text{atoms}=2.55\times 10^{26}\ \text{atoms}\times \dfrac{1\ \text{mol}}{6.022\times 10^{23}\ \text{atoms}}\\\\=423.44\ \text{mol}[/tex]
It means there are 423.44 moles in [tex]2.55\times 10^{26}\ \text{atoms}[/tex] of Neon.
