An attempt is made here to extend this approach to reactants whose functionality is between 1 and 2, and also to arrive at a formula to calculate the number average molecular weight of such a system.Eby Thomas ThachilDepartment of Polymer Science and Rubber TechnologyPolymer-Plastics Technology...
When a subscript, such as “n” in the generic formula [***]n, is used to depict the number of repeating units in a polymer's chemical formula, the formula should be interpreted to represent the number average molecular weight of the macromolecule. The term “individual” includes humans ...

Based on microscopic studies, the haploid chromosome number has been variously reported as 40–43, with a diploid number of about 90 and an average molecular weight per chromosome of 4 × 109 Da (about 6 Mb) (Mohberg, 1977), although there have been reports that the chromosome number varie...
The average isotopic mass of an isotopic mixture for an element in a defined environment on Earth determines the element’s standard atomic weight. A little more than three-quarters of naturally occurring elements exist as a mixture of isotopes, and the average isotopic mass of an isotopic ...
The number density can be used to calculate the average distance between particles and their average collision rate. 2. Solid State Physics In solid-state physics, number density provides information about the arrangement of atoms or molecules within a solid material. It helps determine the packing...
However, should the mass* not be calculated using 340g/mole instead of 660g/mole since that is the average molecular weight* of a single RNA molecule? Unless one has to consider the dsDNA* that is formed during the PCR?? Any explanation would help clear my confusion... Thanks! ams Sat...
b) bis-structure succinimide dispersant (nitrogen content 0.018 wt %, prepared by reaction between polyalkylene polyamine (containing nitrogen atoms of 5.0 (mean number) in a molecule) and a product produced by thermal reaction of polybutene (number average molecular weight: approx. 1,000, having...
