Molar Susceptibility: Determining Unpaired Electrons

The video tutorial explains the concept of susceptibility, focusing on the calculation of molar susceptibility and the spin-only magnetic moment. It discusses the practical approach to identifying compounds, particularly iron, and determining whether they are high spin or low spin. The tutorial provides empirical data and demonstrates the calculation process to determine the number of unpaired electrons, assuming room temperature conditions.
