Three: two hydrogen atoms and one oxygen atom. Hence the formula, H2O.
A molecule of of water contain 3 atoms.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
Vinegar is a dilute solution of acetic acid. The acid molecule contains 7 atoms and the water molecule has 3 atoms. The number of atoms in vinegar cannot be counted.
H2O. Two atoms of hydrogen and one 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.

H2OCount two atoms hydrogen in one molecule of water.
The chemical formula of water is H2O; the molecule contain 3 atoms.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
There are 3 atoms in a water molecule (H2O) - 2 hydrogen atoms and 1 oxygen atom.
there are 2 atoms of hydrogen in water
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
A water molecule (H2O) contain two hydrogen atoms.
the water molecule is H2O so it has 2 atoms of hydrogen in it. (plus an atom of oxygen)
The chemical formula of water is H2O; water contain two hydrogen atoms.
