What is the monoisotopic mass of proline? 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: 97.052
The monoisotopic mass of proline is 97.052 The chemical formula of proline is C5H7ON Formula: Monoisotopi mass= Hence, the monoisotopic mass of proline=5 x (12.000) + 7 x (1.0078) + (15.9949) + (14.0031) monoisotopic mass of proline = 97.052.
