you are provided 2 liquids x and y which on mixing they form an ideal solution . at 30 degree the vp of the solution containing 3 moles of x and 1 mole of y and the total vp of the solution is 50 mm of hg . if 4mole of x and 1 mole of y are mixed in another container then the vp of the solution becomes z . if the pure vp of x is 600 mm of hg and pure vp of y is 200 less then x then find out the value of z
