Understanding molecular weight
WebMolecular weight distribution is a key item of information in tailoring polymer structures for different end uses. Manufacturers offer very many different grades of commodity polymers like poly (vinyl chloride), polyethylenes and polystyrenes. These grades differ significantly between themselves. WebThe difference is that molecular mass is the mass of one specific particle or molecule, while the molar mass is an average over many particles or molecules. The formula weight is a …

WebFeb 14, 2024 · Molecular weight is the mass of a molecule of a substance. It can also be called molecular mass. The units for molecular weight are atomic mass units (amu). Molar mass is the mass of one mole of a … WebThe M+ peak is the largest atomic weight peak referred to as the molecular ion peak. It's essentially the entire molecule, minus a single electron, turning it into what we call a radical cation. This is more or less your molecular weight of your molecule. The M+1 peak would just be the peak with an atomic mass 1 greater than the M+ peak.
