Answer:
The answer is 4.52 × 10²³ molecules
Explanation:
The number of water molecules 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 = 0.75 × 6.02 × 10²³
We have the final answer as
4.52 × 10²³ molecules
Hope this helps you
