The molar mass of glacial acetic acid is 60.05 g/mole. This value represents the mass of one mole of glacial acetic acid molecules. The molar mass is calculated by adding the atomic masses of all the atoms in the chemical formula of the compound. The chemical formula for glacial acetic acid is CH3COOH.

Glacial Acetic Acid Molar Mas

The atomic masses of carbon (C), hydrogen (H), and oxygen (O).

  1. Carbon (C): 12.01 g/mol
  2. Hydrogen (H): 1.01 g/mol
  3. Oxygen (O): 16.00 g/mol
The molecular formula for glacial acetic acid consists of 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms. Therefore, the molar mass of glacial acetic acid is calculated as follows.

Molar mass = (2 x Atomic mass of C) + (4 x Atomic mass of H) + (2 x Atomic mass of O)

Molar mass = (2 x 12.01) + (4 x 1.01) + (2 x 16.00)

Molar mass = 60.05 g/mol

Therefore, the molar mass of glacial acetic acid is 60.05 g/mol.

Acetic Acid Lewis Structure

The Lewis structure of acetic acid (CH3COOH) can be drawn as follows:








The central carbon atom is double-bonded to one oxygen atom and single-bonded to another oxygen atom. The first oxygen atom is also single-bonded to a hydrogen atom, while the second oxygen atom is bonded to a carbon atom and has an additional single bond to the second hydrogen atom.

The carbon and oxygen atoms each have a complete octet and are surrounded by two pairs of non-bonding electrons and two pairs of bonding electrons. Each hydrogen atom has two electrons in its outermost shell.

This Lewis structure shows the bonding and electron distribution in acetic acid and helps explain its chemical properties.

Acetic Acid Properties 

Acetic acid (CH3COOH) is an organic acid. It has both chemical and physical properties that lead to its many uses in industry, medicine, and everyday life.

Physical Properties of Acetic Acid

Appearance: It is a colorless liquid with a pungent odor.

Melting Point: 16.7°C

Boiling Point: 118.1°C
