Considering this, how many moles are 1.20 x1025 atoms of phosphorus?

For phosphorous or any chemical compound, a **mole** contains 6.022⋅1023 molecules in it. So if you have 1.20⋅1025 (that's what I assume you meant) **atoms** of phosphorous, then just divide by Avogadro's number to find the number of **moles**.

Secondly, how many moles are in 20 grams of oxygen? The SI base unit for amount of substance is the mole. **1 mole** is equal to **1 moles** Oxygen, or **15.9994** grams.

Beside this, how many atoms are in .750 moles of zinc?

Since we know that there are **6.022**⋅**1023 atoms** in every mole of a substance (Avogadro's Number), there are **6.022**E23⋅0.750 atoms of Zn in 0.750 mols of Zn.
