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.
One molecule of water contains two atoms of Hydrogen and one atom of Oxygen, which is why its formula is H2O.
The chemical formula of water is H2O. It implies it is made of three atoms.

2The molecular formula of water is H2O. It contains 2 atoms of hydrogen.H2O =2 atoms of hydrogen.
One molecule of water contains two atoms of Hydrogen and one atom of Oxygen, which is why its formula is H2O.
There are two substituents on H2O, which are two hydrogen atoms bonded to the oxygen atom.
