_{5}H

_{5}N

_{2}] Molecular Weight Calculation

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

_{5}H

_{5}N

_{2}. From the chemical formula, you can find that one molecule of Pyrazole consists of five Carbon (C) atoms, five Hydrogen (H) atoms, and two Nitrogen (N) 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)

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

Number of Carbon atoms in Pyrazole: 5

Atomic weight of Carbon (C): 12.0107

Total weight of Carbon atoms in Pyrazole: 12.0107 x 5 = 60.0535

Number of Hydrogen atoms in Pyrazole: 5

Atomic weight of Hydrogen (H): 1.008

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

Number of Nitrogen atoms in Pyrazole: 2

Atomic weight of Nitrogen (N): 14.00674

Total weight of Nitrogen atoms in Pyrazole: 14.00674 x 2 = 28.01348

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

Molecular weight of Pyrazole: 60.0535 (Carbon) + 5.04 (Hydrogen) + 28.01348 (Nitrogen) = 93.10698

So the molecular weight of Pyrazole is 93.10698.
