The molecular weight of 2-Ethoxyethyl acetate [CH₃COOCH₂CH₂OC₂H₅] is 132.1584.

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-Ethoxyethyl acetate [CH₃COOCH₂CH₂OC₂H₅] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a 2-Ethoxyethyl acetate molecule.
From the chemical formula, you will know different atoms and their number in a 2-Ethoxyethyl acetate molecule. Chemical formula of 2-Ethoxyethyl acetate is C₆H₁₂O₃. From the chemical formula of 2-Ethoxyethyl acetate, you can find that one molecule of 2-Ethoxyethyl acetate has six Carbon (C) atoms, twelve Hydrogen (H) atoms and three 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 2-Ethoxyethyl acetate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in 2-Ethoxyethyl acetate: 6
Atomic weight of Carbon: 12.0107
Total weight of Carbon atoms in 2-Ethoxyethyl acetate: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in 2-Ethoxyethyl acetate: 12
Atomic weight of Hydrogen: 1.008
Total weight of Hydrogen atoms in 2-Ethoxyethyl acetate: 1.008 x 12 = 12.096

Number of Oxygen atoms in 2-Ethoxyethyl acetate: 3
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in 2-Ethoxyethyl acetate: 15.9994 x 3 = 47.9982

Step 4: Calculate the molecular weight of 2-Ethoxyethyl acetate by adding up the total weight of all atoms.

Molecular weight of 2-Ethoxyethyl acetate: 72.0642 (Carbon) + 12.096 (Hydrogen) + 47.9982 (Oxygen) = 132.1584

So the molecular weight of 2-Ethoxyethyl acetate is 132.1584.
