100g of liquid A (molar mass 140g `"mol"^(-1)`) was dissolved in 1000g of liquid B (molar mass 180g `"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.
