_{3})

_{2}NCH

_{2}COOH] Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Dimethylglycine molecule.**From the chemical formula, you will know different atoms and their number in a Dimethylglycine molecule. The chemical formula of Dimethylglycine is (CH

_{3})

_{2}NCH

_{2}COOH. From the chemical formula of Dimethylglycine, you can find that one molecule of Dimethylglycine consists of four 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 Dimethylglycine molecule by multiplying its atomic weight by its number.**

Number of Carbon atoms in Dimethylglycine: 4

Atomic weight of Carbon (C): 12.0107

Total weight of Carbon atoms in Dimethylglycine: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Dimethylglycine: 9

Atomic weight of Hydrogen (H): 1.008

Total weight of Hydrogen atoms in Dimethylglycine: 1.008 x 9 = 9.072

Number of Nitrogen atoms in Dimethylglycine: 1

Atomic weight of Nitrogen (N): 14.00674

Total weight of Nitrogen atoms in Dimethylglycine: 14.00674 x 1 = 14.00674

Number of Oxygen atoms in Dimethylglycine: 2

Atomic weight of Oxygen (O): 15.9994

Total weight of Oxygen atoms in Dimethylglycine: 15.9994 x 2 = 31.9988

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

Molecular weight of Dimethylglycine: 48.0428 (Carbon) + 9.072 (Hydrogen) + 14.00674 (Nitrogen) + 31.9988 (Oxygen) = 103.12034

So the molecular weight of Dimethylglycine is 103.12034.
