"WebMolecular weight is not the same as molecular mass. It is also known as relative molecular mass (symbol Mr, where r is a subscript). Molecular weight is defined as the ratio of the mass of a macromolecule to 1/12 the mass of a carbon 12 atom. It is a dimensionless quantity. When the literature gives a mass in Da or kDa it refers to molecular mass. " - Mass to charge ratio in sds-page
