Avogadro's Number - The Mole

The video tutorial introduces Avogadro's number, explaining its role in determining the number of particles in a mole. It covers the mass of atoms and molecules using Avogadro's number, clarifying the difference between chlorine atoms and molecules. Avogadro's hypothesis is discussed, highlighting its importance in gas volume calculations. An example calculation demonstrates how to find the volume of oxygen gas using molar volume at room temperature.
