The video tutorial explains how to determine the empirical and molecular formulas of eugenol, a compound found in oil of cloves. It begins by discussing the molar mass and percentage composition of carbon, hydrogen, and oxygen in eugenol. The tutorial then demonstrates how to calculate the mass and moles of each element, leading to the derivation of the molecular formula. Finally, it simplifies the molecular formula to find the empirical formula, emphasizing the difference between the two.
