Answer:

28.24 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

[tex]n = \frac{1.7 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 28.2392...[/tex]

We have the final answer as

28.24 moles

Hope this helps you
