What Is Avogadro's Number - The Mole

The video tutorial introduces Amedeo Avogadro, an Italian scientist known for Avogadro's number, which is the number of particles in a mole. It explains how the mass of Avogadro's number of atoms or molecules relates to their relative atomic or molecular mass in grams. The tutorial also covers Avogadro's hypothesis, which states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. This concept simplifies gas calculations, as demonstrated in an example where the volume of oxygen gas is calculated using molar volume.
