# Diethyl Ether [(CH3CH2)2O] Molecular Weight Calculation

The molecular weight of Diethyl ether [C4H10O] is 74.1222. Diethyl ether [(CH3CH2)2O] is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Diethyl ether is 74.1222 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Diethyl ether [C4H10O] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Diethyl ether molecule.
From the chemical formula, you will know different atoms and their number in a Diethyl ether molecule. Chemical formula of Diethyl ether is C4H10O. From the chemical formula of Diethyl ether, you can find that one molecule of Diethyl ether has four Carbon (C) atoms, ten 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 Diethyl ether molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Diethyl ether: 4
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in Diethyl ether: 12.0107 x 4 = 48.0428

Number of Hydrogen atoms in Diethyl ether: 10
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in Diethyl ether: 1.008 x 10 = 10.08

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

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

Molecular weight of Diethyl ether: 48.0428 (Carbon) + 10.08 (Hydrogen) + 15.9994 (Oxygen) = 74.1222

So the molecular weight of Diethyl ether is 74.1222.
