Answer:

9.42 moles

Step-by-step explanation:

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


n = (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{5.67 * {10}^(25) }{6.02 * {10}^(23) } \\ = 9.418604...

We have the final answer as

9.42 moles

Hope this helps you
