Question

4. How many of moles of FeO are in 3.6 x 1024 molecules of this compound?

Answer 1

The answer is 5.98 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{3.6 * {10}^(24) }{6.02 * {10}^(23) } \\ = 5.98006644...`

We have the final answer as

5.98 moles
