Answer:
The answer is
<h3>2.53 × 10²⁴ molecules</h3>
Explanation:
The number of molecules present can be found by using the formula
<h3>N = n × L</h3>
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 = 4.21 × 6.02 × 10²³
We have the final answer as
<h3>2.53 × 10²⁴ molecules</h3>
