The molecular weight of Benzoxazole (C7H5NO) is 119.12104.
Benzoxazole (C7H5NO) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Benzoxazole is 119.12104 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Benzoxazole [C7H5NO] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Benzoxazole molecule.
You will know different atoms and their number in a Benzoxazole molecule from the chemical formula. The chemical formula of Benzoxazole is C7H5NO. From the chemical formula, you can find that one molecule of Benzoxazole consists of seven Carbon (C) atoms, five 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 Benzoxazole molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Benzoxazole: 7
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Benzoxazole: 12.0107 x 7 = 84.0749
Number of Hydrogen atoms in Benzoxazole: 5
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Benzoxazole: 1.008 x 5 = 5.04
Number of Nitrogen atoms in Benzoxazole: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Benzoxazole: 14.00674 x 1 = 14.00674
Number of Oxygen atoms in Benzoxazole: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Benzoxazole: 15.9994 x 1 = 15.9994
Step 4: Calculate the molecular weight of Benzoxazole by adding up the total weight of all atoms.
Molecular weight of Benzoxazole: 84.0749 (Carbon) + 5.04 (Hydrogen) + 14.00674 (Nitrogen) + 15.9994 (Oxygen) = 119.12104
So the molecular weight of Benzoxazole is 119.12104.
