Definition and Calculation of Relative Molecular Mass

Relative molecular mass (also known as molecular weight) is the ratio of the mass of a molecule to the mass of a carbon12 atom. For L-Phenylalaninol, the calculation of its relative molecular mass is based on the following atomic masses:  

Carbon (C): 12.01  

Hydrogen (H): 1.01  

Nitrogen (N): 14.01  

Oxygen (O): 16.00  

The calculation steps are as follows:  

Total mass of carbon atoms: 9 × 12.01 = 108.09  

Total mass of hydrogen atoms: 13 × 1.01 = 13.13  

Total mass of nitrogen atoms: 1 × 14.01 = 14.01  

Total mass of oxygen atoms: 1 × 16.00 = 16.00  

Adding these masses together gives the relative molecular mass of L-Phenylalaninol :  

108.09 + 13.13 + 14.01 + 16.00 = 151.21 g/mol.
