The vapour density of completely dissociated would be — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

The vapour density of completely dissociated 4 NH Cl is half than that of pure 4 NH Cl . Because no. of moles after dissociation becomes double and molar mass comes out to be half.
