The vapour pressure of pure water at 25°c is 18 mm Hg . When a nonelectrolyte is dissolved, its vapour pressure becomes 17.32 mm Hg . What is the relative lowering of vapour pressure of the solution?
We have given, The vapour pressure of pure water at 25°C = 18mm Hg. After addition of non-electrolyte, the vapour pressure of water = 17.32 mm Hg. Then, lowering in vapour pressure = (18...
