Three, two hydrogen and one oxygen. The suffix after the H tells you that there two, no suffix after O tells you there is only one.
The H2O molecule (a k a water) consists of 2 hydrogen atoms and one oxygen atom, therefore it consists of 3 atoms and 2 elements.
3. Two hydrogen atoms, one oxygen atom.
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
Water contain thee atoms in the molecule.

There are 2 hydrogen atoms and 1 oxygen.
One molecule of H2O has 3 atoms (two hydrogens and one oxygen). So there will be 12 atoms in 4H2O.
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
Water contain thee atoms in the molecule.
There is 1 O atom in 1 H2O molecule thus there are 12 O atoms in 12 H2O molecules.

2The molecular formula of water is H2O. It contains 2 atoms of hydrogen.H2O =2 atoms of hydrogen.
That varies with the substance. H2O is composed of 3 atoms. C6H12O6 is composed of 24 atoms.
There are 2 hydrogen atoms and 1 oxygen.
