What is the monoisotopic mass of glycine? Given data: Mass of the most abundant isotope of Carbon (C°)=12.0000, Mass of most abundant isotope of Hydrogen (H°)=1.0078, Mass of most abundant isotope of Oxygen (O°)=15.9949, Mass of most abundant isotope of Nitrogen (N°)=14.0031.

Correct Answer: 57.0214
The monoisotopic mass of glycine is 57.0214. The chemical formula of Glycine is C2H3ON Formula: Monoisotopic mass = Hence, the monoisotopic mass of glycine=2 x (12.000) + 3 x (1.0078) + (15.9949) + (14.0031) monoisotopic mass of glycine = 57.0214.
