one oxygen
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
One molecule of water contains two atoms of Hydrogen and one atom of Oxygen, which is why its formula is H2O.
there is only 1 atom of oxygen in water [H2O]. hope this helps =]
There are 3 atoms in a water molecule (H2O) - 2 hydrogen atoms and 1 oxygen atom.
There is 1 O atom in 1 H2O molecule thus there are 12 O atoms in 12 H2O molecules.
One atom.
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
There are two substituents on H2O, which are two hydrogen atoms bonded to the oxygen atom.
Three: two hydrogen atoms and one oxygen atom. Hence the formula, H2O.
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
Water molecules, H2O, have two different types of atoms. They are hydrogen (H), and oxygen (O).
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
