How many atoms are there in one molecule of H3PO4? How many atoms of each element are there in this molecule

The number after the element symbols tells you how many are in one molecule.
H3 --> 3 Hydrogen atoms
P --> 1 Phosphorous atom (it's one, if there is no number...)
O4 --> 4 Oxygen atoms
Adding them up you have 8 atoms in a molecule of H3PO4
Another example, water is H2O (2 Hydrogen, 1 Oxygen), for a total of 3 atoms...
