Lactic Acid O-carboxyanhydride (C4H4O4) Molecular Weight Calculation

The molecular weight of Lactic acid O-carboxyanhydride (C4H4O4) is 116.0724.

Lactic acid O-carboxyanhydride (C4H4O4) 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: Lactic acid O-carboxyanhydride (C4H4O4) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Lactic acid O-carboxyanhydride molecule.
From the chemical formula, you will know different atoms and their number in a Lactic acid O-carboxyanhydride molecule. Chemical formula of Lactic acid O-carboxyanhydride is C4H4O4. From the chemical formula of Lactic acid O-carboxyanhydride, you can find that one molecule of Lactic acid O-carboxyanhydride has four Carbon (C) atoms, four 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 Lactic acid O-carboxyanhydride molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Lactic acid O-carboxyanhydride: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Lactic acid O-carboxyanhydride: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Lactic acid O-carboxyanhydride: 4
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Lactic acid O-carboxyanhydride: 1.008 x 4 = 4.032

Number of Oxygen atoms in Lactic acid O-carboxyanhydride: 4
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Lactic acid O-carboxyanhydride: 15.9994 x 4 = 63.9976

Step 4: Calculate the molecular weight of Lactic acid O-carboxyanhydride by adding up the total weight of all atoms.

Molecular weight of Lactic acid O-carboxyanhydride: 48.0428 (Carbon) + 4.032 (Hydrogen) + 63.9976 (Oxygen) = 116.0724

So the molecular weight of Lactic acid O-carboxyanhydride is 116.0724.
