Diglycolic Acid (O(CH2COOH)2) Molecular Weight Calculation

The molecular weight of Diglycolic acid (O(CH2COOH)2) is 134.0878.

Diglycolic acid (O(CH2COOH)2) 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: Diglycolic acid (O(CH2COOH)2) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Diglycolic acid molecule.
From the chemical formula, you will know different atoms and their number in a Diglycolic acid molecule. Chemical formula of Diglycolic acid is C4H6O5. From the chemical formula of Diglycolic acid, you can find that one molecule of Diglycolic acid has four Carbon (C) atoms, six Hydrogen (H) atoms and five 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 Diglycolic acid molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Diglycolic acid: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Diglycolic acid: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Diglycolic acid: 6
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Diglycolic acid: 1.008 x 6 = 6.048

Number of Oxygen atoms in Diglycolic acid: 5
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Diglycolic acid: 15.9994 x 5 = 79.997

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

Molecular weight of Diglycolic acid: 48.0428 (Carbon) + 6.048 (Hydrogen) + 79.997 (Oxygen) = 134.0878

So the molecular weight of Diglycolic acid is 134.0878.
