The weight-average molecular mass Mw (2.82 × 106 to 5.11 × 106 Da), number-average molecular mass Mn (0.43 × 106 to 2.01 × 106 Da) and dispersity index Mw/Mn (2.54–6.64) of SFPG filtrate were relatively high. Using a capillary viscometer, the intrinsic viscosity of various ...

Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
Related to molecular weights:Molar mass molecular weight,weight of amoleculeof a substance expressed inatomic mass units(amu). The molecular weight may be calculated from the molecularformulaof the substance; it is the sum of theatomic weightsof the atoms making up the molecule. For example, wa...
作者: JC Quintanilla 摘要: The molecular weight is the sum of the masses of the atoms making up a molecule expressed in atomic units of mass. One atomic unit of mass, or Dalton (Da), is equal to 1/12 the mass of an atom of the... DOI: 10.1007/978-3-642-27833-4_1020-3 收藏...
The molecular weight changes in abiotically and biotically degraded LDPE and LDPE modified with starch and/or prooxidant were compared with the formation of degradation products. The samples were thermooxidized for 6 days at 100C to initiate degradation and then either inoculated with Arthobacter pa...

to 1/12 of the mass of carbon 12 and is a dimensionless number. Thus, it is incorrect to express relative molecular mass (molecular weight) in Daltons (Da) or kilo-Daltons (kDa) (unfortunately, the terms molecular weight and molecular mass have been confused on numerous websites, which ...
A computer program is described that will determine the molecular weight of DNA, RNA or protein molecules separated according to size by gel electrophoresis. It uses the sizes and migration distances of known molecules in a reference lane to compute a second or third order equation whose curve be...
