Answer:

<h2>0.17 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

We have

n =  \frac{1.00 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{1}{6.02}  \\   = 0.166112

We have the final answer as

<h3>0.17 moles</h3>
