(JEE Advanced 2021) Which of the following concentration terms change with density? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Molarity, Normality, and % w/v are volume-based. Volume is linked to mass via density ($V = m/d$). Molality depends on mass only, so it is independent of density changes (unless the solution preparation itself involves volume).
