The molar mass of a single oxygen atom is 15.9994, so double that in order to find the molar mass of O2. Finding molar mass starts with units of grams per mole (g/mol). More exact masses are found in scientific references—for example, the exact mass of uranium-238 is 238.050788 u, so you can see that we are not far off by using the whole-number value as the mass of the atom. Hydrogen (H) Kilogram per mole (kg/mol) Molecular oxygen (O 2) is a diatomic molecule that is composed of two oxygen atoms held together by a covalent bond. Molar mass of O = 15.9994 g/mol. Thus, the mass of carbon-12 is about 12 u, the mass of oxygen-16 is about 16 u, and the mass of uranium-238 is about 238 u. = 1.0938 mol. Add up your answers to get 18, and the molecular mass of Oxygen and Hydrogen which is water gives you 18. ›› Oxygen molecular weight. [Relative molecular mass of ammonium nitrate is 80, H = 1, N= 14, 0= 16], mean mass per particle in terms of the atomic mass unit (amu), which, for our purposes, we declare to be the proton mass, m p.
