Description: WEBDec 6, 2022 · The molecular mass, often called the molecular weight (MW), is the weight of all atoms in a given molecular formula. Molecular weight is measured in Atomic Mass Units, usually expressed as u or amu. In order to calculate the molecular weight of a formula, you'll need to add up the atomic masses of each element present.
