How many moles are in 3.00x 10^22 atoms of He?
sp2606 [1]

Answer:

<h2>0.05 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{3.0 \times  {10}^{22} }{6.02 \times  {10}^{23} }  \\  = 0.049833...

We have the final answer as

<h3>0.05 moles</h3>

Hope this helps you
