Answer 1

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.
