The molecular weight of 2-Ethoxyethanol [C2H5OCH2CH2OH] is 90.1216.
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: 2-Ethoxyethanol [C2H5OCH2CH2OH] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a 2-Ethoxyethanol molecule.
From the chemical formula, you will know different atoms and their number in a 2-Ethoxyethanol molecule. Chemical formula of 2-Ethoxyethanol is C4H10O2. From the chemical formula of 2-Ethoxyethanol, you can find that one molecule of 2-Ethoxyethanol has four Carbon (C) atoms, ten Hydrogen (H) atoms and two Oxygen (O) atoms.
Step 2: Find out atomic weights of each atom (from periodic table).
Step 3: Calculate the total weight of each atom present in a 2-Ethoxyethanol molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in 2-Ethoxyethanol: 4
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in 2-Ethoxyethanol: 12.0107 x 4 = 48.0428
Number of Hydrogen atoms in 2-Ethoxyethanol: 10
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in 2-Ethoxyethanol: 1.008 x 10 = 10.08
Number of Oxygen atoms in 2-Ethoxyethanol: 1
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in 2-Ethoxyethanol: 15.9994 x 2 = 31.9988
Step 4: Calculate the molecular weight of 2-Ethoxyethanol by adding up the total weight of all atoms.
Molecular weight of 2-Ethoxyethanol: 48.0428 (Carbon) + 10.08 (Hydrogen) + 31.9988 (Oxygen) = 90.1216
So the molecular weight of 2-Ethoxyethanol is 90.1216.
