Adipic acid [HOOC(CH2)4COOH] is an organic compound of three elements: Carbon, Hydrogen and Oxygen. The molecular weight of Adipic acid [HOOC(CH2)4COOH] is 146.1418 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Carbon, Hydrogen and Oxygen.

Adipic acid [HOOC(CH2)4COOH] Molecular Weight CalculationTo calculate molecular weight of any compound, the first step is to know the constituent atoms and their number in that particular compound. Then calculate the total weight of each atom by multiplying its atomic weight by its number. The sum of total weight of all constituent atoms will be the molecular weight of the compound. Note that the value of atomic weight may differ slightly from different sources.

CALCULATION PROCEDURE: Adipic Acid [HOOC(CH2)4COOH] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Adipic Acid molecule.
From the chemical formula, you will know different atoms and their number in a Adipic Acid molecule. Chemical formula of Adipic Acid is C6H10O4. From the chemical formula of Adipic Acid, you can find that one molecule of Adipic Acid has six Carbon (C) atoms, ten Hydrogen (H) atoms and four 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 Oxygen (O) : 15.9994 (Ref: Jlab-ele008)

Step 3: Calculate the total weight of each atom present in a Adipic Acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Adipic Acid: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Adipic Acid: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Adipic Acid: 10
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Adipic Acid: 1.008 x 10 = 10.08

Number of Oxygen atoms in Adipic Acid: 4
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Adipic Acid: 15.9994 x 4 = 63.9976

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

Molecular weight of Adipic Acid: 72.0642 (Carbon) + 10.08 (Hydrogen) + 63.9976 (Oxygen) = 146.1418

So the molecular weight of Adipic Acid is 146.1418.
