# CALCULATION PROCEDURE: 3,5-Diphenyl-isoxazole  [C15H11NO] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a 3,5-Diphenyl-isoxazole molecule.
You will know different atoms and their number in a 3,5-Diphenyl-isoxazole molecule from the chemical formula. The chemical formula of 3,5-Diphenyl-isoxazole is C15H11NO. From the chemical formula, you can find that one molecule of 3,5-Diphenyl-isoxazole consists of fifteen Carbon (C) atoms, eleven 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 a 3,5-Diphenyl-isoxazole molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in 3,5-Diphenyl-isoxazole: 15
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in 3,5-Diphenyl-isoxazole: 12.0107 x 15 = 180.1605

Number of Hydrogen atoms in 3,5-Diphenyl-isoxazole: 11
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in 3,5-Diphenyl-isoxazole: 1.008 x 11 = 11.088

Number of Nitrogen atoms in 3,5-Diphenyl-isoxazole: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in 3,5-Diphenyl-isoxazole: 14.00674 x 1 = 14.00674

Number of Oxygen atoms in 3,5-Diphenyl-isoxazole: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in 3,5-Diphenyl-isoxazole: 15.9994 x 1 = 15.9994

Step 4: Calculate the molecular weight of 3,5-Diphenyl-isoxazole by adding up the total weight of all atoms.

Molecular weight of 3,5-Diphenyl-isoxazole: 180.1605 (Carbon) + 11.088 (Hydrogen) + 14.00674 (Nitrogen) + 15.9994 (Oxygen) = 221.25464

So the molecular weight of 3,5-Diphenyl-isoxazole is 221.25464.
