You probable think to sodium sulfate, Na2SO4.
Na2SO4 has: 7 atoms total - 2 sodium, 1 sulfur and 4 oxygen.
2Na2SO4 (two molecules) have 14 atoms.
There are a total of 16 atoms in the formula 2Na2SO4. This includes 4 Na atoms, 2 S atoms, and 8 O atoms.
There are a total of 38 atoms in 2Na2SO4 (sodium sulfate). This includes 4 sodium atoms, 2 sulfur atoms, and 8 oxygen atoms.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
There are 4 calcium atoms, 8 chlorine atoms, and 2 carbon atoms in 4CaCl2 (calcium chloride).
There are a total of 16 atoms in the formula 2Na2SO4. This includes 4 Na atoms, 2 S atoms, and 8 O atoms.
In the formula Na2SO4, there are 2 sodium (Na) atoms, 1 sulfur (S) atom, and 4 oxygen (O) atoms.
