How many moles are in 3.86 x 1023 molecules of Carbon Dioxide (CO2)?
Yuri [45]

Answer:

<h2>0.64 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{3.86 \times {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{3.86}{6.02}  \\  = 0.641196...

We have the final answer as

<h3>0.64 moles</h3>

Hope this helps you
