Question

83. The total vapour pressure of a solution of methanol
and ethanol in an ideal solution is given by P =
135 a + 100 (where a = mole fraction of
methanol). Pure state vapour pressure of methanol
is
(1) 235 mm ug
(3) 35 mm ug
(2) 100 mm ug
(4) 135 mm ug​

Answer 1

Answer:

third option is right option

Answer 2

Answer:

P=135a+100

now let's assume a=1

Pmethanol= 135(1)+100

Pmethanol=235mmug

so 1 is correct
