The answer is 1.50 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{9.01 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{9.01}{6.02}  \\  = 1.496677740...

We have the final answer as

1.50 moles

Hope this helps you
