The molecular weight of Isoxazole (C3H3NO) is 119.12104.

Isoxazole [C3H3NO] Molecular Weight CalculationIsoxazole (C3H3NO) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Isoxazole is 69.06224 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Isoxazole  [C3H3NO] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Isoxazole molecule.
You will know different atoms and their number in an Isoxazole molecule from the chemical formula. The chemical formula of Isoxazole is C3H3NO. From the chemical formula, you can find that one molecule of Isoxazole consists of three Carbon (C) atoms, three Hydrogen (H) atoms, one Nitrogen (N) atom, and one Oxygen (O) 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 Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

Number of Carbon atoms in Isoxazole: 3
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Isoxazole: 12.0107 x 3 = 36.0321

Number of Hydrogen atoms in Isoxazole: 3
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Isoxazole: 1.008 x 3 = 3.024

Number of Nitrogen atoms in Isoxazole: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Isoxazole: 14.00674 x 1 = 14.00674

Number of Oxygen atoms in Isoxazole: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Isoxazole: 15.9994 x 1 = 15.9994

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

Molecular weight of Isoxazole: 36.0321 (Carbon) + 3.024 (Hydrogen) + 14.00674 (Nitrogen) + 15.9994 (Oxygen) = 69.06224

So the molecular weight of Isoxazole is 69.06224.
