Answer:
The answer is
2.049 × 10²⁴ particles
Explanation:
To find the number of entities or particles given the number of moles of a substance we use 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
n = 3.4 mol
We have
N = 3.4 × 6.02 × 10²³
We have the final answer as
2.049 × 10²⁴ particles
Hope this helps you
