Answer:
<h2>3.003 × 10²⁴ molecules</h2>
Explanation:
The number of molecules can be found by using the formula
N = 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 = 4.99 × 6.02 × 10²³
We have the final answer as
<h3>3.003 × 10²⁴ molecules</h3>
Hope this helps you
