The molecular weight of Asparagine [C₄H₈N₂O₃] is 132.11848.

Asparagine (C₄H₈N₂O₃) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Asparagine is 132.11848 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Asparagine  [C₄H₈N₂O₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Asparagine molecule.
From the chemical formula, you will know different atoms and their number in an Asparagine molecule. The chemical formula of Asparagine is C₄H₈N₂O₃. From the chemical formula, you can find that one molecule of Asparagine consists of four Carbon (C) atoms, eight Hydrogen (H) atoms, two Nitrogen (N) atoms, and three 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 an Asparagine molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Asparagine: 4
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Asparagine: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Asparagine: 8
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Asparagine: 1.008 x 8 = 8.064

Number of Nitrogen atoms in Asparagine: 2
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Asparagine: 14.00674 x 2 = 28.01348

Number of Oxygen atoms in Asparagine: 3
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Asparagine: 15.9994 x 3 = 47.9982

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

Molecular weight of Asparagine: 48.0428 (Carbon) + 8.064 (Hydrogen) + 28.01348 (Nitrogen) + 47.9982 (Oxygen) = 132.11848

So the molecular weight of Asparagine is 132.11848.
