As 3H3PO4 , there are 9(nine) hydrogen atoms.
3H3PO4 means that there are 3 (three) molecules of phosphoric acid. ;
3H3PO4 = H3PO4 + H3PO4 + H3PO4
However, as one molecule of phosphoric acid, there are only 3 (three) atoms of hydrogen present.
The structure of phosphoric acid (as best I can show it is ;_
P(=O) (-OH)3
That is one phosphorus atom double bonded to one oxygen atom, and three hydroxide groups directly bonded to the phosphorus.
In 3H3PO4, there are 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 4 additional hydrogen atoms for a total of 19 atoms.
There are a total of 17 atoms in 3H3PO4. This includes 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 1 carbon atom.
