Acetic Acid (CH3COOH): An Introduction

Acetic acid, known by its chemical formula CH3COOH, is a familiar and essential compound in both natural and industrial contexts. It is the main component of vinegar, providing its characteristic sour taste and pungent odor. Beyond its culinary significance, acetic acid finds applications in a range of industries, including food processing, pharmaceuticals, and chemical manufacturing.

Breaking Down the Molecular Weight

The molecular weight of any compound is determined by summing the atomic masses of all the atoms present in one molecule of that compound. To calculate the molecular weight of acetic acid (CH3COOH), we must consider the atomic masses of its constituent elements:

1. Carbon (C): Carbon has an atomic mass of approximately 12.01 grams/mole (g/mol).
2. Hydrogen (H): Hydrogen has an atomic mass of approximately 1.01 g/mol.
3. Oxygen (O): Oxygen has an atomic mass of around 16.00 g/mol.

Let’s delve into the calculations:

Molecular Weight of CH3COOH = (Atomic Mass of C) + (2 * Atomic Mass of H) + (2 * Atomic Mass of O)

Molecular Weight of CH3COOH = (12.01 g/mol) + (2 * 1.01 g/mol) + (2 * 16.00 g/mol)

Molecular Weight of CH3COOH = 12.01 g/mol + 2.02 g/mol + 32.00 g/mol

Molecular Weight of CH3COOH ≈ 60.03 grams/mole

Therefore, the molecular weight of acetic acid (CH3COOH) is approximately 60.03 grams per mole.
