4.5Molecular weight Themolecular weight(formula weight) of a compound is the sum of the atomic weights of all the atoms in a molecule and can be determined by a variety of methods. Crude oil, being a complex mixture of (at least) several thousand constituents requires qualification of the mo...
The meaning of MOLECULAR WEIGHT is the average mass of a molecule of a compound compared to 1/12 the mass of carbon 12 and calculated as the sum of the atomic weights of the constituent atoms.
