_{4}] Molecular Weight Calculation

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

_{3}N

_{2}H

_{4}. From the chemical formula, you can find that one molecule of Imidazole consists of three Carbon (C) atoms, four Hydrogen (H) atoms, two 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): 28.01348 (Ref: Jlab-ele007)

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

Number of Carbon atoms in Imidazole: 3

Atomic weight of Carbon (C): 12.0107

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

Number of Nitrogen atoms in Imidazole: 2

Atomic weight of Nitrogen (N): 28.01348

Total weight of Nitrogen atoms in Imidazole: 28.01348 x 2 = 28.01348

Number of Hydrogen atoms in Imidazole: 4

Atomic weight of Hydrogen (H): 1.008

Total weight of Hydrogen atoms in Imidazole: 1.008 x 4 = 4.032

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

Molecular weight of Imidazole: 36.0321 (Carbon) + 28.01348 (Nitrogen) + 4.032 (Hydrogen) = 68.07758

So the molecular weight of Imidazole is 68.07758.
