PLS HELP - How many moles are present in 3.01 x 1023 atoms of N2 (nitrogen gas) ?
Neporo4naja [7]

Answer:

<h2>0.5 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{3.01 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{3.01}{6.02}  = 0.5 \\

We have the final answer as

<h3>0.5 moles </h3>

Hope this helps you
