IIT/JEE Chemistry Practice #3: Empirical/Molecular Formula

Dave explains how to solve a problem involving empirical and molecular formulas of a hydrocarbon. The problem provides data on carbon and hydrogen mass ratios and conditions of the hydrocarbon vapor. Using the ideal gas law, the number of moles is calculated, followed by determining the molar mass. The empirical formula is derived by converting mass to moles and finding the carbon to hydrogen ratio. The empirical formula matches the molecular formula, concluding the problem with C7H8 as the answer.
