Answer:

b. 0.50 moles

Explanation:

To solve this problem we use Avogadro's number (6.023x10²³ atoms/mol).

By dividing the number of atoms (or molecules) by that number, 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.
