The Total solution for NCERT class 6-12
100 g of liquid A (molar mass 140g mol−1) was dissolved in 1000 g 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.
