How To Use Moles - Part 1

The video tutorial introduces Avogadro's number and its significance in chemistry, explaining how it relates to moles and the relative atomic mass of elements. It discusses the concept of comparing equal numbers of particles in compounds, using examples like FeCl3 and Fe2O3 to illustrate the calculation of moles in compounds. The tutorial also covers the idea of relative molecular mass and the flexibility of using fractions of moles in calculations, emphasizing the relative nature of these numbers.
