Is molecular weight and mass the same? Molecular mass and Molecular weight is not the same, although they use interchangeably. ... Molecular weight, as a synonym of molar mass, is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured...
but the two words don't mean the same thing. The difference between mass and weight is that mass is the amount ofmatterin a material, while weight is a measure of how the force of gravity acts upon that mass.1
In chemistry, there are different types of mass. Often, the terms are called weight rather than mass and used interchangeably. A good example is molecular mass or molecular weight. Molecular Mass Definition Molecular mass is a number equal to the sum of theatomic massesof theatomsin amolecule....

The atomic weight of an atom, or the molecular weight of a molecule, is its mass relative to that ofa___ atom. This is essentially equal to the number of protons plus neutrons that the atom or molecule contains. A oxygen B hydrogen C helium D carbon 相关知识点: 试题来源: 解析 B ...
Since the light scattered by a protein is directly proportional to its weight-average molecular mass and concentration, molecular masses were calculated from the light-scattering and interferometric refractometer data using ASTRA 6.1 software. 2.7. In vivo sterol export from mutant yeast cells ...

mass shift of +105.0215 Da at the lysine residue position H3K23 (Supplementary Fig.1a). The same mass shift of +105.0215 Da was also found in other histone lysine residues, including H3K122, H4K77, and H4K91, as well as non-histone lysine residues including HNRNPC K243 and ...
Example: A bowling ball and a basketball are about the same volume as each other, but the bowling ball has much more mass. To be precise when using measurement terms, make sure you know thedifference between mass and weight.
