Answer:

The answer is 82,724.25 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{4.98 \times {10}^{28} }{6.02 \times {10}^{23} } \\ = 82724.2524...[/tex]

We have the final answer as

82,724.25 moles
