This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar ...

The Système International (SI) base unit for mass is the kilogram. But this is a rather large mass to use for general laboratory work in chemistry. So chemists prefer to use the relative molecular mass or formula mass in grams (1000 g = 1 kg). You can find the number of moles ...

In order to determine the number of moles of a given compound, the first thing you need to do is find the molecular mass (or molecular weight) of the compound in question. Once you've done that, you need to determine how much the compound weighs physical
mass units, or amu. Therefore, if the molecular weight of a substance represents the number of grams required for 1 mole, then the number of moles represented by any given amount of substance will be equal to the grams of that substance divided by its molecular weight. Mathematically, this ...
