The molecular formula of water is H2O. It contains 2 atoms of hydrogen.
H2O =2 atoms of hydrogen.
Water's chemical formula is H2O. This means that twohydrogen atoms are contained in it as well as one oxygen.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
hydrogen oxide is water or H2O and has two hydrogens
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.
6 : 4 hydrogen 2 oxygen ------------------------------------ That would be for two water molecules as one is H20 - therefore 3 atoms
For the water molecule (H2O) two hydrogen atoms are needed.
there are 2 atoms of hydrogen in water
2 hydrogen atoms per molecule of water.
H2OCount two atoms hydrogen in one molecule of water.
There are three atoms in a molecule of water. One oxygen atom and 2 hydrogen atoms. The simplified form for the molecule of water is H2O which is a coded form for the 2 hydrogen and 1 oxygen atoms that make up the molecule.
the water molecule is H2O so it has 2 atoms of hydrogen in it. (plus an atom of oxygen)
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
A water molecule (H2O) contain two hydrogen atoms.
There are 2 hydrogen atoms present in each water molecule. This can be seen from the formula for water H2O -- this tells us there are 2 atoms of hydrogen combined with 1 atom of oxygen
there are 2 atoms of hydrogen in water
Per every water molecule, there are 2 hydrogen atoms and 1 oxygen atom. These atoms make up a water molecule.
H20, so that would be two hydrogen atoms.
