22. A piece of wood board contains approximately 6.76 X 1023 molecules of wood, C2H4920, how
Licemer1 [7]

Answer:

<h2>1.23 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

From the question we have

n =  \frac{6.76 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{6.76}{6.02}  \\  = 1.22923...

We have the final answer as

<h3>1.23 moles</h3>

Hope this helps you
