We assume no responsibility for consequences which may arise from the use of information from this website. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. 1 See answer Advertisement This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. m = mass = #"g"# Note that rounding errors may occur, so always check the results. One mole is equal to 6.022141791023 atoms, or other elementary units such as molecules. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. (The measurement was made by X-ray scattering.) Alternatively we can do the calculation directly like with carbon: \[16\,\cancel{u} \times \dfrac{1.6605 \times 10^{24}\, g}{1 \,\cancel{u}} = 2.66 \times 10^{23} \, g \text{ (per oxygen atom)} \nonumber\].
