b. 0.50 moles
Explanation:
To solve this problem we use <em>Avogadro's number</em> (6.023x10²³ atoms/mol).
By <u>dividing the number of atoms (or molecules) by that number</u>, we can calculate how many moles they represent.
- 3.01x10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.50 moles
So the answer is option b. 0.50 moles.
