100 g of liquid A `(molar mass 140 g mol^-1)` was dissolved in 1000g of liquid B `(molar mass 180 g mol^-1)`. The vapour pressure of pure liquid B was found to be 500 torr: Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 Torr.
