Dimethoxymethane [C3H8O2] Molecular Weight Calculation

The molecular weight of Dimethoxymethane [C3H8O2] is 76.0949.

Dimethoxymethane [C3H8O2] 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: Dimethoxymethane [C3H8O2] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Dimethoxymethane molecule.
From the chemical formula, you will know different atoms and their number in a Dimethoxymethane molecule. Chemical formula of Dimethoxymethane is C3H8O2. From the chemical formula of Dimethoxymethane, you can find that one molecule of Dimethoxymethane has three Carbon (C) atoms, eight Hydrogen (H) atoms and two 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 Dimethoxymethane molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Dimethoxymethane: 3
Atomic weight of
Carbon (C): 12.0107
Total weight of Carbon atoms in Dimethoxymethane: 12.0107 x 3 = 36.0321

Number of Hydrogen atoms in Dimethoxymethane: 8
Atomic weight of
Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Dimethoxymethane: 1.008 x 8 = 8.064

Number of Oxygen atoms in Dimethoxymethane: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Dimethoxymethane: 15.9994 x 2 = 31.9988

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

Molecular weight of Dimethoxymethane: 36.0321 (Carbon) + 8.064 (Hydrogen) + 31.9988 (Oxygen) = 76.0949

So the molecular weight of Dimethoxymethane is 76.0949.
