Glutamic Acid HOOCCH(NH₂)(CH₂)₂COOH₂ is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Glutamic acid is 147.12984 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Glutamic acid  [HOOCCH(NH₂)(CH₂)₂COOH₂] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Glutamic acid molecule.
From the chemical formula, you will know different atoms and their number in a Glutamic acid molecule. The chemical formula of Glutamic acid is HOOCCH(NH₂)(CH₂)₂COOH₂ (C₅H₉NO₄). From the chemical formula of Glutamic acid, you can find that one molecule of Glutamic acid consists of five Carbon (C) atoms, nine Hydrogen (H) atoms, one Nitrogen (N) atom, and four 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 Glutamic acid molecule by multiplying its atomic weight by its number.

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

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

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

Number of Oxygen atoms in Glutamic Acid: 4
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Glutamic Acid: 15.9994 x 4 = 63.9976

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

Molecular weight of Glutamic Acid: 60.0535 (Carbon) + 9.072 (Hydrogen) + 14.00674 (Nitrogen) + 63.9976 (Oxygen) = 147.12984

So the molecular weight of Glutamic Acid is 147.12984.
