5.01 moles of magnesium phosphate contain how many atoms of phosphorus?

Explanation:

Deal with 1 mole first.

The chemical formula of Magnesium Phosphate is

Mg3(PO4)2

The 2 tells you that there are 2 mols of Phosphorus in the chemical.

1 mol of anything is 6.02 * 10^23 (in this case) atoms.

2 mols of anything is 12.04 * 10^23 atoms

2 moles of anything is 1.204 * 10^24 (the 2 answers are the same. This one is more correct in scientific notation.)

Now we come to the 5.01. Where does that go?

5.01 * Mg3(PO4)2

So multiply 1.204 * 10^24 by 5.01 When you do, you get

7.26 * 10^24 atoms

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
