The molecular weight of Pyrazole (C₅H₅N₂) is 93.10698.

Pyrazole (C₅H₅N₂) is an organic compound of three elements: Carbon, Hydrogen, and Nitrogen. The molecular weight of Pyrazole is 93.10698 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Pyrazole  [C₅H₅N₂] 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 C₅H₅N₂. 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.
