Elemental Analysis: Empirical and Molecular Formulas

The video tutorial explains elemental analysis, focusing on hydrocarbons. It introduces the concept of empirical formulas and describes a method to determine the carbon-to-hydrogen ratio in hydrocarbons through combustion. The process involves using an apparatus to measure the mass of carbon dioxide and water produced. The tutorial uses benzene as an example to calculate percent composition and derive its empirical and molecular formulas, demonstrating the steps to find the actual number of atoms in a molecule.

Explain the process of combustion of hydrocarbons and its significance in determining the empirical formula.
