A single molecule of water consists of three atoms. H2O is built from a single atom of oxygen that is single-bonded with two atoms of hydrogen.
atoms in a drop of water = 3 atoms/molecule x 1.67 x 10 21 molecules; atoms in a drop of water = 5.01 x 10 21 atoms; Or, there are about 5 sextillion atoms in a drop of water. Atoms in a Drop of Water vs. Drops in the Ocean. One interesting question is whether there are more atoms in a drop of water than there are drops of water in the ocean. To determine the answer, we need the volume of water in the oceans. Sources estimate this to be between 1.3 billion km 3 and 1.5 km 3.
