How to get the molecular formula from the burning reaction فكرة مهمة

For secondary two This guide explains the essential steps to determine the molecular formula of an organic compound using data from its combustion reaction. By analyzing the masses of carbon dioxide (CO₂) and water (H₂O) produced during complete combustion, you can calculate the amounts of carbon and hydrogen in the original sample. If oxygen is present, its mass is found by difference. The process involves converting experimental data into moles, determining the empirical formula, and—when the molar mass is known—deriving the true molecular formula.
