Thiazole (C_{3}H_{3}NS) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Sulfur. The molecular weight of Thiazole is 85.12884 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

**CALCULATION PROCEDURE: Thiazole [C**_{3}H_{3}NS] Molecular Weight Calculation

_{3}H

_{3}NS] Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Thiazole molecule.**You will know different atoms and their number in a Thiazole molecule from the chemical formula. The chemical formula of Thiazole is C

_{3}H

_{3}NS. From the chemical formula, you can find that one molecule of Thiazole consists of three Carbon (C) atoms, three Hydrogen (H) atoms, one Nitrogen (N) atom, and one Sulfur atom.

**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 Sulfur (S): 32.066 (Ref: Jlab-ele016)

**Step 3: Calculate the total weight of each atom in a Thiazole molecule by multiplying its atomic weight by its number.**

Number of Carbon atoms in Thiazole: 3

Atomic weight of Carbon (C): 12.0107

Total weight of Carbon atoms in Thiazole: 12.0107 x 3 = 36.0321

Number of Hydrogen atoms in Thiazole: 3

Atomic weight of Hydrogen (H): 1.008

Total weight of Hydrogen atoms in Thiazole: 1.008 x 3 = 3.024

Number of Nitrogen atoms in Thiazole: 1

Atomic weight of Nitrogen (N): 14.00674

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

Number of Sulfur atoms in Thiazole: 1

Atomic weight of Sulfur (S): 32.066

Total weight of Sulfur atoms in Thiazole: 32.066 x 1 = 32.066

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

Molecular weight of Thiazole: 36.0321 (Carbon) + 3.024 (Hydrogen) + 14.00674 (Nitrogen) + 32.066 (Sulfur) = 85.12884

So the molecular weight of Thiazole is 85.12884.
