Many common preparatory sources use g/mol and effectively define it as a synonym of molar mass, while more authoritative sources use Da or u and align its definition more closely with the molecular mass. Molecular Weight Search Help Search options (step 1) (Back to search) You may search for species based on molecular weight values in two ways: Specify a single value; the system will search for values within 0.5 units of this value.

The mass of the nitrogen atom is 14 amu. The molecular weight of the nitrogen molecule is 28 amu as the nitrogen molecule has two atoms of nitrogen. The molar mass of the nitrogen molecule is Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids (DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. Molecular weight of N 2 is 2*14.0067 g/mol, 78.084% of air Molecular weight of O 2 is 2*15.9994 g/mol, 20.946% of air Molecular weight of Ar is 39.948 g/mol, 0.9340% of air Nucleic Acid Molecular Weight Conversions Exact M.W. of ssRNA (e.g., RNA Transcript): M.W. = (An x 329.2) + (Un x 306.2) + (Cn x 305.2) + (Gn x 345.2) + 159 ª An The molecular weight is very commonly used as a synonym of molar mass, particularly for molecular compounds; however, the most authoritative sources define it differently (see molecular mass). The formula weight is a synonym of molar mass that is frequently used for non-molecular compounds, such as ionic salts .
