This site explains how to find molar mass. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. molar mass and molecular weight. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. The reason is that the molar mass of the substance affects the conversion. The mass of a one-mole molecule of a compound is equal to the sum of the molar mass numbers of constituents atoms, expressed in the units of a gram. common chemical compounds. We use the most common isotopes. - Definition, Formula & Examples, Working Scholars® Bringing Tuition-Free College to the Community.
