Answer 1

To determine the number of atoms in the formula Na2HPO4, we can break it down:

• Na2 means there are 2 sodium (Na) atoms.
• H means there is 1 hydrogen (H) atom.
• P means there is 1 phosphorus (P) atom.
• O4 means there are 4 oxygen (O) atoms.

Now, we can add them up:

• 2 (from Na) + 1 (from H) + 1 (from P) + 4 (from O) = 8 atoms.

So, the correct response is eight.
