How many moles of glucose C6H12O6 are in a sample which weighs The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. We use the most common isotopes. 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 mass, which may also be called standard atomic weight or average atomic mass.
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. 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 A common request on this site is to convert grams to moles.
