Answer:
The answer is
[tex] 2.143 \times {10}^{18} \: \: atoms[/tex]
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
[tex]n = 3.559 \times {10}^{ - 6} \: mol[/tex]
Substitute the values into the above formula and solve
That's
[tex]N = 3.559 \times {10}^{ - 6} \times 6.02 \times {10}^{23} \\ = 2.1425 \times {10}^{18} [/tex]
We have the final answer as
[tex]N = 2.143 \times {10}^{18} \: \: atoms[/tex]
Hope this helps you
