MHT CET 2024 Chemistry question
Calculate the relative lowering of vapour pressure of solution containing 46 g of non-volatile solute in 162 g of water at [Molar mass of non-volatile solute = 46 g ]
Answer: (C)
Solution
Moles of solute mol; moles of water mol. By Raoult's law the relative lowering of vapour pressure equals the mole fraction of the solute, (exact). Using the dilute-solution form taught in the
