How many moles are in 4.35 X 1024 atoms of Iron (Fe)?
Naya [18.7K]

Answer:

<h3>The answer is 7.23 moles</h3>

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{4.35 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 7.225913...

We have the final answer as

<h3>7.23 moles</h3>

Hope this helps you
