Answer:

[tex] \huge 2.541 \times {10}^{16} \: \: moles \\ [/tex]

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{1.53 \times {10}^{40} }{6.02 \times {10}^{23} } \\ \\ = 2.541 \times {10}^{16} \: \: moles[/tex]

Hope this helps you
