Molecular weight can be determined by different methods including cryoscopy, ebulliometry, viscometry etc. The osmotic pressure method is the most suitable method for determining the molar mass of a polymer. ![]() Key Features of Determination of Molecular WeightĪs the molecular weight increases, mechanical properties increase. ![]() The boiling point of a compound increases with an increase in molecular weight. Molecular weight can be determined by colligative properties calculation methods. Therefore, by using these formulas we can find out the molar mass of unknown compounds. With the help of this knowledge, one can also conclude that the freezing point formula is as follows ![]() In most cases, the freezing point formula is usually proportional to the molality of the solute that is added. From this freezing point depression definition, it must be clear that this is a colligative property of solutions. Colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent particles in a solution, and not on the nature of the particles present.ĭetermination of Molecular Weight of Non-Volatile Soluteįreezing point depression can be defined as the phenomenon of lowering the freezing point of any solvents after the addition of solutes. The cryoscopic method is one of the best methods used to determine the molecular mass of a non-volatile solute, as we have, ΔT f =K f .m where, ΔT f is calculated experimentally and K f is constant and by using molality we can easily find the molecular weight of the solute particle. ![]()
