# Dimethyl Ether (CH3OCH3) Molecular Weight Calculation

The molecular weight of Dimethyl ether (CH3OCH3) is 46.0688.

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: Dimethyl ether (CH3OCH3) Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Dimethyl ether molecule.
From the chemical formula, you will know different atoms and their number in a Dimethyl ether molecule. Chemical formula of Dimethyl ether is C2H6O. From the chemical formula of Dimethyl ether, you can find that one molecule of Dimethyl ether has two Carbon (C) atoms, six Hydrogen (H) atoms and one Oxygen (O) atom.

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 Dimethyl ether molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Dimethyl ether: 2
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Dimethyl ether: 12.0107 x 1 = 24.0214

Number of Hydrogen atoms in Dimethyl ether: 6
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Dimethyl ether: 1.008 x 6 = 6.048

Number of Oxygen atoms in Dimethyl ether: 1
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Dimethyl ether: 15.9994 x 1 = 15.9994

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

Molecular weight of Dimethyl ether: 24.0214 (Carbon) + 6.048 (Hydrogen) + 15.9994 (Oxygen) = 46.0688

So the molecular weight of Dimethyl ether is 46.0688.
