The mass of a single water molecule is 2.9907x10-23 g to five significant figures, or 2.9907 times one hundredth of a millionth of a millionth of a nanogram, which is itself one billionth of a gram. This of course cannot be directly measured; we instead have to indirectly measure the mass of one molecule.
