The molecular weight of Sarcosine [CH₃N(H)CH₂CO₂H] is 89.09364.

Sarcosine (CH₃N(H)CH₂CO₂H) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Sarcosine is 89.09364 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Sarcosine  [CH3N(H)CH2CO2H] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Sarcosine molecule.
From the chemical formula, you will know different atoms and their number in a Sarcosine molecule. The chemical formula of Sarcosine is CH₃N(H)CH₂CO₂H. From the chemical formula of Sarcosine, you can find that one molecule of Sarcosine consists of three Carbon (C) atoms, seven 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 an Alanine molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Sarcosine: 3
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Sarcosine: 12.0107 x 3 = 36.0321

Number of Hydrogen atoms in Sarcosine: 7
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Sarcosine: 1.008 x 7 = 7.056

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

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

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

Molecular weight of Sarcosine: 36.0321 (Carbon) + 7.056 (Hydrogen) + 14.00674 (Nitrogen) + 31.9988 (Oxygen) = 89.09364

So the molecular weight of Sarcosine is 89.09364.
