Benzothiazole (C7H5NS) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Sulfur. The molecular weight of Benzothiazole is 135.18764 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Benzothiazole [C7H5NS] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Benzothiazole molecule.
You will know different atoms and their number in a Benzothiazole molecule from the chemical formula. The chemical formula of Benzothiazole is C7H5NS. From the chemical formula, you can find that one molecule of Benzothiazole consists of seven Carbon (C) atoms, five Hydrogen (H) atoms, one Nitrogen (N) atom, and one Sulfur 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 Sulfur (S): 32.066 (Ref: Jlab-ele016)
Step 3: Calculate the total weight of each atom in a Benzothiazole molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Benzothiazole: 7
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Benzothiazole: 12.0107 x 7 = 84.0749
Number of Hydrogen atoms in Benzothiazole: 5
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Benzothiazole: 1.008 x 5 = 5.04
Number of Nitrogen atoms in Benzothiazole: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Benzothiazole: 14.00674 x 1 = 14.00674
Number of Sulfur atoms in Benzothiazole: 1
Atomic weight of Sulfur (S): 32.066
Total weight of Sulfur atoms in Benzothiazole: 32.066 x 1 = 32.066
Step 4: Calculate the molecular weight of Benzothiazole by adding up the total weight of all atoms.
Molecular weight of Benzothiazole: 84.0749 (Carbon) + 5.04 (Hydrogen) + 14.00674 (Nitrogen) + 32.066 (Sulfur) = 135.18764
So the molecular weight of Benzothiazole is 135.18764.
