two
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
This is one atom of oxygen in a molecule of water. There are two atoms of hydrogen in that same molecule.
There are two hydrogen atoms in one molecule of water (H2O).
The molar mass of a substance in daltons is the mass of one mole of that substance, measured in daltons.
One molecule of water contains 2 atoms of Hydrogen - and 1 atom of Oxygen.
The chemical formula for water is H2O. The subscripted "2" indicates that there are two atoms of hydrogen in one water molecule. No subcripted number means there is just one atom in the molecule, meaning there are two hydrogen atoms and one oxygen atom.
