Answer:
1.806 × 10²³ atoms
Explanation:
The number of sodium atoms 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 = 0.3 × 6.02 × 10²³
We have the final answer as
1.806 × 10²³ atoms
Hope this helps you
