Which of the following statements correctly relate the concepts of absolute density and vapour densi — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Statement A is true; Vapour Density is a ratio of two masses (or densities), so units cancel out. Statement B is true; from the Ideal Gas Law, $d = \frac{PM}{RT}$, so $d \propto M$ at constant P and T. Statement C is false; Vapour Density relies solely on molar mass ($M/2$) which is an intrinsic property of the gas and independent of temperature. Statement D is the standard equation for standard vapour density relative to $H_2$.
