Answer:
The answer is
Explanation:
To find the number of moles given the number of entities of an element we use the formula
[tex]n = \frac{N }{L} \\ [/tex]
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
N = 9.6 x 10²⁵ atoms of Oxygen
So we have
[tex]n = \frac{9.6 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 159.46843...[/tex]
We have the final answer as
