Molecular weight Chem., the weight of a molecule of any gas or vapor as compared with the hydrogen atom having weight of 1 as a standard; the sum of the atomic weights of the constituents of a molecule; thus, the molecular weight of water (H2O) is 18. For more precise measurements, the weight of the carbon isotope carbon-12 is used as the standard, that isotope having the value of 12.000. In this systen, now used almost universally, the hydrogen atom has a weight of 1.0079.
adj 1: relating to or produced by or consisting of molecules;
"molecular structure"; "molecular oxygen"; "molecular
weight is the sum of all the atoms in a molecul"
2: relating to simple or elementary organization; "proceed by
more and more detailed analysis to the molecular facts of
perception"--G.A. Miller [syn: molecular(a)] [ant: molar(a)]
