The Mole: Avogadro's Number and Stoichiometry

The video tutorial explains the concept of moles in chemistry, highlighting their importance in stoichiometry and chemical reactions. It introduces Avogadro's number and explains how moles serve as a bridge between atomic mass units and grams. The tutorial also covers the calculation of molar mass and demonstrates stoichiometric calculations, using propane combustion as an example to predict the mass of products formed. The video emphasizes the practical application of these calculations in technology and experiments.
