More information on molar mass and molecular weight

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in achemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

The atomic weights used on this site come from NIST, the National Institute ofStandards and Technology. 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 asmolecular 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 atomicweight or average atomic mass.

Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from thechemical equation are sometimes called equation weights.

A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying toconvert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.
