# Acetic Acid (CH3COOH) Molecular Weight Calculation

The molecular weight of acetic acid (CH3COOH) is 60.052. Acetic acid (CH3COOH) 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 (CH3COOH) 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 CH3COOH. 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.
