The answer is 7.24 × 10-¹² moles

Explanation:

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

$n = \frac{N}{L} \\$

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

$n = \frac{4.36 \times {10}^{12} }{6.02 \times {10}^{23} } \\$

We have the final answer as

7.24 × 10-¹² moles

Hope this helps you
