Some Basic Concepts of Chemistry — NEET/JEE Questions, Notes & Weightage
Class 11 Basic Concepts & Atomic Structure NEET weightage: High 64 questions
Covers mole concept, atomic/molecular mass, stoichiometry, limiting reagent, and concentration terms (molarity, molality, normality). The foundational numericals chapter — mole-concept and stoichiometry calculations appear in nearly every NEET/JEE Chemistry paper, often disguised inside other chapters' questions.

Frequently asked questions
Why is this chapter important beyond its own questions?
Mole-concept calculations (limiting reagent, molarity, percentage composition) are the base skill almost every numerical chapter later — Equilibrium, Electrochemistry, Solutions — assumes you already have cold.
What numerical type is asked most directly?
Limiting reagent problems and converting between molarity/molality/mole fraction are the most frequently repeated direct question formats.
