Three, two hydrogen and one oxygen. The suffix after the H tells you that there two, no suffix after O tells you there is only one.
There are two atoms of hydrogen in one molecule of H2O.
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
There are 3 atoms in a water molecule (H2O) - 2 hydrogen atoms and 1 oxygen atom.
There are two substituents on H2O, which are two hydrogen atoms bonded to the oxygen atom.
One molecule of water contains two atoms of Hydrogen and one atom of Oxygen, which is why its formula is H2O.
