molecular weight The sum of the atomic weights of the atoms contained in a molecule. For example, since the atomic weight of hydrogen is 1 and the atomic weight of oxygen is 16, the molecular weight of water (H2O) is 1 + 1 + 16, or 18. ...

IN recent years, light-scattering techniques have been widely used for the determination of micellar molecular weights. On the other hand, a few workershave chosen to make such determinations through measurement of colligative properties, in particular, by measurement of the lowering of the vapour ...
