Answer:

423.44 moles

Step-by-step explanation:

We need to find no of moles in
2.55* 10^(26)\ \text{atoms} of Neon.

We know that,


1\ \text{mol of atoms}=6.022* 10^(23)\ \text{atoms}


2.55* 10^(26)\ \text{atoms}=2.55* 10^(26)\ \text{atoms}* \frac{1\ \text{mol}}{6.022* 10^(23)\ \text{atoms}}\\\\=423.44\ \text{mol}

It means there are 423.44 moles in
2.55* 10^(26)\ \text{atoms} of Neon.
