**Answer:**

19.9 moles

**Explanation:**

Each mole has 6.02 x 10^23 many atoms. This number is commonly known as "Avogadro's Number."

In this problem, we have 1.2 x 10^25 atoms of phosphorus.

Thus, (1.2 x 10^25)/(6.02 x 10^23) is the number of moles in 1.20 x 10^25 many atoms of phosphorus.

(1.2(10^25))/(6.02(10^23))

19.9 moles.
