peer agreement (net): +2względne masy cząsteczkowe Explanation: W praktyce, w związku z trudnościami technicznymi w wyrażaniu rzeczywistych mas cząsteczkowych, stosuje się tak zwane względne masy cząsteczkowe, obliczane jako suma względnych mas atomowych tworzących ją atomów. Względna masa cząsteczkowa jest wielkością bezwymiarową, którą należy rozumieć jako wielokrotność 1/12 masy atomu izotopu węgla 12C. https://pl.wikipedia.org/wiki/Masa_cząsteczkowa cccccccccccccccccccccccccc A more proper term would be "relative molecular mass". However the adjective 'relative' is omitted as it is universally assumed that atomic and molecular masses are relative to the mass of 12C. Relative atomic and molecular mass values are dimensionless but are given the "unit" Dalton (formerly atomic mass unit) to indicate that the number is equal to the mass of one molecule divided by 1⁄12 of the mass of one atom of 12C. The mass of 1 mol of substance is designated as molar mass. By definition, it has the unit gram. https://en.wikipedia.org/wiki/Molecular_mass |

| Reference: relative molecular mass Reference information: The sum of all the relative atomic masses of the atoms in a molecule; the ratio of the average mass per molecule of a specified isotopic composition of a substance to one-twelfth the mass of an atom of carbon-12 M r, r.m.m. Former name molecular weight http://www.dictionary.com/browse/relative-molecular-mass -------------------------------------------------- Note added at 36 mins (2017-07-29 10:27:18 GMT) -------------------------------------------------- There appears to be no general consensus on a common trivial name for this agent: α-chlorohydrin and 3-monochloro-1,2-propanediol are equally used; however, a preference for 3-monochloro-1,2-propanediol, and especially the abbreviation 3-MCPD, was noted in the more recent literature. - https://monographs.iarc.fr/ENG/Monographs/vol101/mono101-010... |
