# CALCULATION PROCEDURE: Clavulanic acid [C8H9NO5] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Clavulanic acid molecule.
You will know different atoms and their number in a Clavulanic acid molecule from the chemical formula. Chemical formula of Clavulanic acid is C8H9NO5. From the chemical formula, you can find that one molecule of Clavulanic acid has eight Carbon (C) atoms, nine Hydrogen (H) atoms, one Nitrogen (N) atom, and five Oxygen (O) atoms.

Step 2: Find out atomic weights of each atom (from 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 present in a Clavulanic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Clavulanic acid: 8
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Clavulanic acid: 12.0107 x 8 = 96.0856

Number of Hydrogen atoms in Clavulanic acid: 9
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Clavulanic acid: 1.008 x 9 = 9.072

Number of Nitrogen atoms in Clavulanic acid: 1
Atomic weight of Nitrogen: 14.00674
Total weight of Nitrogen atoms in Clavulanic acid: 14.00674 x 1 = 14.00674

Number of Oxygen atoms in Clavulanic acid: 5
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Clavulanic acid: 15.9994 x 5 = 79.997

Step 4: Calculate the molecular weight of Clavulanic acid by adding up the total weight of all atoms.

Molecular weight of Clavulanic acid: 96.0856 (Carbon) + 9.072 (Hydrogen) + 14.00674 (Nitrogen) + 79.997 (Oxygen) = 199.16134

So the molecular weight of Clavulanic acid is 199.16134.
