In this session, we focus on Relative Atomic Mass (Ar) — a key part of the Atomic Structure chapter. This class explains how atomic masses are calculated and why they are not whole numbers. What You’ll Learn in This Class: 1️⃣ Understanding Relative Atomic Mass (Ar) What Ar means and how it differs from mass number Why elements have fractional atomic masses How isotopes affect Ar values 2️⃣ Calculating Ar Using Isotopic Abundance Step-by-step method for calculating weighted average Practice problems using real exam-style data Importance of units and significant figures 3️⃣ Application of Ar in Chemistry Role of Ar in mole calculations and chemical equations Using the Periodic Table effectively Interpreting questions that involve Ar values 4️⃣ Solved Past Paper Questions Multiple choice and structured questions broken down clearly How to show working and impress examiners Common errors in Ar calculations and how to avoid them Why Join Mega Lecture? Mega Lecture helps students master Chemistry topics with crystal-clear explanations, real examples, and consistent past paper practice.
