Explanation:
To find the number of atoms given the number of moles we use the formula
N = n × L
where
N is the number of entities
n is the number of moles
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>
