Glycine (C_{2}H_{5}NO_{2}) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Glycine is 75.06694 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

**CALCULATION PROCEDURE: Glycine [C**_{2}H_{5}NO_{2}] Molecular Weight Calculation

_{2}H

_{5}NO

_{2}] Molecular Weight Calculation

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

_{2}H

_{5}NO

_{2}. From the chemical formula of Glycine, you can find that one molecule of Glycine consists of two Carbon (C) atoms, five 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 Glycine molecule by multiplying its atomic weight by its number.**

Number of Carbon atoms in Glycine: 2

Atomic weight of Carbon (C): 12.0107

Total weight of Carbon atoms in Glycine: 12.0107 x 2 = 24.0214

Number of Hydrogen atoms in Glycine: 5

Atomic weight of Hydrogen (H): 1.008

Total weight of Hydrogen atoms in Glycine: 1.008 x 5 = 5.04

Number of Nitrogen atoms in Glycine: 1

Atomic weight of Nitrogen (N): 14.00674

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

Number of Oxygen atoms in Glycine: 2

Atomic weight of Oxygen (O): 15.9994

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

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

Molecular weight of Glycine: 24.0214 (Carbon) + 5.04 (Hydrogen) + 14.00674 (Nitrogen) + 31.9988 (Oxygen) = 75.06694

So the molecular weight of Glycine is 75.06694.
