At 323 K, the vapour pressure in millimeters of mercury of a methanol-ethanol solution is represented by the equation p = 120 X A + 140, where X A is the mole fraction of methanol. Then the value of 
is
Text Solution
Verified by ExpertsThe correct answer is:
C
As X A ⎯→ 1. Then we will have pure methanol so P T = 120 X A + 140 = 120 + 140 = 260 mm of Hg.
