What is the oxidation number for oxygen? These relative weights computed from the chemical equation are sometimes called equation weights. 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 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. 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 to convert.

The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass. We use the most common isotopes.
