# Acetic Oxalic Anhydride (C6H6O6) Molecular Weight Calculation

The molecular weight of Acetic oxalic anhydride (C6O6H6) is 174.1086.

To 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: Acetic oxalic anhydride (C6O6H6) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Acetic oxalic anhydride molecule.
From the chemical formula, you will know different atoms and their number in a Acetic oxalic anhydride molecule. Chemical formula of Acetic oxalic anhydride is C6H6O6. From the chemical formula of Acetic oxalic anhydride, you can find that one molecule of Acetic oxalic anhydride has six Carbon (C) atoms, six Hydrogen (H) atoms and six 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 Acetic oxalic anhydride molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Acetic oxalic anhydride: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Acetic oxalic anhydride: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Acetic oxalic anhydride: 6
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Acetic oxalic anhydride: 1.008 x 6 = 6.048

Number of Oxygen atoms in Acetic oxalic anhydride: 6
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Acetic oxalic anhydride: 15.9994 x 6 = 95.9964

Step 4: Calculate the molecular weight of Acetic oxalic anhydride by adding up the total weight of all atoms.

Molecular weight of Acetic oxalic anhydride: 72.0642 (Carbon) + 6.048 (Hydrogen) + 95.9964 (Oxygen) = 174.1086

So the molecular weight of Acetic oxalic anhydride is 174.1086.
