Solutions · Raoult's law vapour pressure
At T(K), 2 moles of liquid A and 3 moles of liquid B are mixed. The vapour pressure of ideal solution formed is 320 mm Hg. At this stage, one mole of A and one mole of B are added to the solution. The vapour pressure is now measured as 328.6 mm Hg. The vapour pressures (in mm Hg) of A and B are respectively:
- (1)300, 200
- (2)600, 400
- (3)400, 300
- (4)500, 200
We corrected a printing error in the original paper
Source printed “The vapour pressure (in mm Hg) of A and B are”.
