Answer:
The answer is 0.03 moles
Explanation:
To find the number of moles given the number of entities 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 = 2 × 10²² molecules of water
We have
[tex]n = \frac{2 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.033222591...[/tex]
We have the final answer as
0.03 moles
Hope this helps you
