Class 10 Chemistry | Chapter 15 | Molar Volume & Concentration of Solution | Lecture 1 | PECTAA 2026

Class 10 Chemistry Chapter 15 Lecture 1 | Stoichiometry | New Book 2026 Punjab Board In this lecture, we start Chapter 15: Stoichiometry from the Class 10 Chemistry New Book 2026. This lesson covers the concepts of Molar Volume of Gases at RTP, Concentration of Solutions, and solved numerical examples from the textbook. Students will learn how to calculate the number of moles, volume of gases at RTP, concentration in g/dm³ and mol/dm³, and solve exam-style numerical questions step by step. Topics Covered: ✅ Introduction to Stoichiometry ✅ Molar Volume of Gases at RTP ✅ Relationship Between Moles and Volume ✅ Solved Numerical Problems (15.1, 15.2, 15.3) ✅ Concentration of Solution ✅ Mass/Volume Concentration (g/dm³) ✅ Molar Concentration (mol/dm³) ✅ Important Board Exam Numericals ✅ Quick Checks and Concept Building Formulas Covered: Moles = Volume ÷ Molar Volume Volume = Moles × Molar Volume Concentration = Mass of Solute ÷ Volume of Solution Molar Concentration = Moles of Solute ÷ Volume of Solution 🎯 Ideal for: Class 10 Students Punjab Board Students SSC Part-II Chemistry School Tests & Board Exams Entry-Level Chemistry Learners 📚 Chapter 15 – Stoichiometry 📖 Punjab Curriculum & Textbook Board (PCTB) New Chemistry Book 2026 If this lecture helps you, please Like, Share, and Subscribe for more Chemistry, Physics, Biology, and Mathematics lectures. #Chemistry10 #Stoichiometry #MolarVolume #ConcentrationOfSolution #Class10Chemistry #ChemistryNewBook2026 #PunjabBoard
