Class 10 chapter 15 | Molecular formula with solved examples | examples 15.13 to 15.15 Umair khan

Sir Umair Khan is delivering lecture on molecular formula How it is formulated what is its definition and how can you find out the molecular formula from empirical formula. All these questions are addressed in this lecture. Major highlights of this lecture is the steps which are to be followed for the determination of molecular formula by the help of examples. Short Questions. Define molecular formula. Mathematical expression. What does a complete and balanced chemical equation tell us Examples are included. Benzene is represented by its empirical formula CH while its molecular mass is 78. Find out its molecular formula. 2.Glucose has an empirical formula CH O and its molecular mass is 180 g mol1–. What will be its molecular formula? : 3. 25 g of lime stone (CaCO3) react with an excess of hydrochloric acid according to the above equation. How much calcium chloride (CaCl2) will be produced?
