Answer:

<h2>70.27 moles</h2>

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{4.23 \times  {10}^{25} }{6.02 \times  {10}^{23} }  \\  = 70.265780...

We have the final answer as

<h3>70.27 moles</h3>

Hope this helps you
