How is molecular mass calculated
WebWeight average molecular mass (WAMM) is a measure of the average molecular weight of a population of molecules. It is calculated by taking the weighted sum of all the molecular weights in the population, where the weighting factor is the mole fraction of each molecule. The WAMM can be used to characterize both pure substances and mixtures. Web26 jun. 2024 · the molecular weight usually includes isotopic mass abundances and is not useful for MS (Carbon would not be calculated as c=12u but as a mixture of ~99% 12u and ~1% 12.0034).
