L-6. Avogadro’s Number Explained | Chapter 4 Stoichiometry – 9th Chemistry by Prof. Majid Ali

Описание: Title: Avogadro’s Number Explained | Chapter 4 Stoichiometry – 9th Chemistry by Prof. Majid Ali

Welcome to an in-depth chemistry lecture by **Prof. Majid Ali (Gold Medalist)**! In this video we dive into **Avogadro’s Number (6.022×10²³)**, how it defines one mole, and why it’s essential for understanding stoichiometry. If you're Class 9 or studying chemistry fundamentals, you’ll gain clarity on how atoms, molecules, and particles relate to grams and chemical reactions.

What You’ll Learn

Definition and importance of *Avogadro’s Number (NA)*
How one mole connects atomic mass units (amu) to measurable mass
Representing reactions with large numbers (from atoms to molecules)
How to use Avogadro’s Number in real calculations
Examples & reaction representations for better understanding
