The vapour pressure of two liquids p and q are 80 and 60 Torr, respect...
Solution:


Step 1: Calculate the mole fraction of both the liquids.
Let's assume the mole fraction of liquid p be 'x' and mole fraction of liquid q be 'y'.

Therefore, x = 3/(3+2) = 0.6 and y = 2/(3+2) = 0.4


Step 2: Calculate the partial pressure of each liquid.
Let's assume the total vapour pressure of the solution be 'P'.

Therefore, partial pressure of liquid p = xP = 0.6 x 80 = 48 Torr

And partial pressure of liquid q = yP = 0.4 x 60 = 24 Torr


Step 3: Calculate the total vapour pressure of the solution.
The total vapour pressure of the solution would be the sum of the partial pressures of both the liquids.

Total vapour pressure of the solution = partial pressure of liquid p + partial pressure of liquid q

Total vapour pressure of the solution = 48 + 24 = 72 Torr


Therefore, the correct option is 1) 72 torr.
