Answer:
[tex]2.89 \times {10}^{20} \: \: molecules[/tex]
Explanation:
The number of molecules of KCN can be found by using the formula
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 = 0.00048 × 6.02 × 10²³
We have the final answer as
[tex]2.89 \times {10}^{20} \: \: \: molecules[/tex]
Hope this helps you
