Two hydrogen atoms and one oxygen atom.
It depends on how much water you have!
there are 2 atoms of hydrogen in water
2 hydrogen atoms per molecule of water.
A molecule of of water contain 3 atoms.
H2OCount two atoms hydrogen in one molecule of water.
Water contain thee atoms in the molecule.
The chemical formula of water is H2O. It implies it is made of three atoms.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
water
There are 4 atoms of hydrogen in 2H2O.
The chemical formula of water is H2O; water contain two hydrogen atoms and one oxygen atom: 2 + 1= 3 atoms.
There are 8 oxygen atoms in 4 water molecules.
