D. eight
To determine the number of atoms represented in the formula Na2HPO4, we need to count the individual atoms present in the formula.
The formula Na2HPO4 consists of the elements sodium (Na), hydrogen (H), phosphorus (P), and oxygen (O).
Counting the atoms:
- Sodium (Na) is present as Na2, so we have 2 sodium atoms.
- Hydrogen (H) is present as H, so we have 1 hydrogen atom.
- Phosphorus (P) is present as P, so we have 1 phosphorus atom.
- Oxygen (O) is present as O4, so we have 4 oxygen atoms.
Therefore, by adding up the individual atoms, we have a total of 2 + 1 + 1 + 4 = 8 atoms.
So, the correct answer is D.Eight.
To determine the number of atoms in the formula Na2HPO4, we need to calculate the total number of each element present.
- Na2 (sodium) indicates that there are 2 sodium atoms.
- H (hydrogen) suggests that there is 1 hydrogen atom.
- P (phosphorus) implies that there is 1 phosphorus atom.
- O4 (oxygen) means that there are 4 oxygen atoms.
Adding these numbers together, we get:
2 (sodium atoms) + 1 (hydrogen atom) + 1 (phosphorus atom) + 4 (oxygen atoms) = 8 atoms
Therefore, the formula Na2HPO4 represents 8 atoms in total.
The correct answer is (D) eight.
