The molecular weight of Proline [C5H9NO2] is 115.13104.

Proline [C5H9NO2] Molecular Weight CalculationProline (C5H9NO2) is an organic compound of five elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Proline is 115.13104 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Proline  [C5H9NO2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Proline molecule.
From the chemical formula, you will know different atoms and their number in a Proline molecule. The chemical formula of Proline is C5H9NO2. From the chemical formula of Proline, you can find that one molecule of Proline consists of five Carbon (C) atoms, nine Hydrogen (H) atoms, one Nitrogen (N) atom, and two Oxygen atoms.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of Hydrogen (H): 1.008 (Ref: Lanl-1)

Atomic weight of Nitrogen (N): 14.00674 (Ref: Jlab-ele007)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

Step 3: Calculate the total weight of each atom in a Proline molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Proline: 5
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Proline: 12.0107 x 5 = 60.0535

Number of Hydrogen atoms in Proline: 9
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Proline: 1.008 x 9 = 9.072

Number of Nitrogen atoms in Proline: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Proline: 14.00674 x 1 = 14.00674

Number of Oxygen atoms in Proline: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Proline: 15.9994 x 2 = 31.9988

Step 4: Calculate the molecular weight of Proline by adding up the total weight of all atoms.

Molecular weight of Proline: 60.0535 (Carbon) + 9.072 (Hydrogen) + 14.00674 (Nitrogen) + 31.9988 (Oxygen) = 115.13104

So the molecular weight of Proline is 115.13104.
