Empirical formula

The video tutorial explains the concept of empirical formulas, using calcium chloride as an example, where the empirical formula is CaCl2, indicating two chlorine atoms for each calcium atom. It further discusses how empirical formulas for covalent compounds are often simpler than their molecular formulas, exemplified by glucose, which has a molecular formula of C6H12O6 that simplifies to an empirical formula of CH2O.
