Mean molecular weight refers to the average mass of a molecule in a substance, considering its distribution of molecular weights. This concept is important in fields like chemistry, biochemistry, and materials science, as it provides insights into the size and properties of molecules. Different techniques, such as gel permeation chromatography, light scattering, and mass spectrometry, are used to determine the mean molecular weight of substances. Understanding this average value aids in characterizing materials, determining their physical and chemical properties, and assessing their suitability for specific applications.
