Answer:

12.82 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

From the question we have

[tex]n = \frac{7.72 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 12.8 239[/tex]

We have the final answer as

12.82 moles

Hope this helps you
