The molecular weight of acetic acid (CH_{3}COOH) is 60.052.

Acetic acid (CH_{3}COOH) is an organic compound of three elements: Carbon, Hydrogen, and Oxygen. The molecular weight of Ethanolamine is 60.052 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

**CALCULATION PROCEDURE: Acetic Acid (CH**_{3}COOH) Molecular Weight Calculation

_{3}COOH) Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in an Acetic acid molecule.**You will know different atoms and their number in an acetic acid molecule from the chemical formula. The chemical formula of acetic acid is CH

_{3}COOH. From the chemical formula, you can find that one molecule of acetic acid consists of two Carbon (C) atoms, four Hydrogen (H) atoms, and two Oxygen atoms.

**Step 2: Find out the atomic weights of each atom (from the 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 in an acetic acid molecule by multiplying its atomic weight by its number.**

Number of Carbon atoms in acetic acid: 2

Atomic weight of Carbon (C): 12.0107

Total weight of Carbon atoms in acetic acid: 12.0107 x 2 = 24.0214

Number of Hydrogen atoms in acetic acid: 4

Atomic weight of Hydrogen (H): 1.008

Total weight of Hydrogen atoms in acetic acid: 1.008 x 7 = 4.032

Number of Oxygen atoms in acetic acid: 2

Atomic weight of Oxygen (O): 15.9994

Total weight of Oxygen atoms in acetic acid: 15.9994 x 2 = 31.998

**Step 4: Calculate the molecular weight of acetic acid by adding up the total weight of all atoms. **

Molecular weight of acetic acid (CH3COOH): 24.022 (Carbon) + 4.032 (Hydrogen) + 31.998 (Oxygen) = 60.052

So the molecular weight of acetic acid is 60.052.
