Question

The vapour pressure of two liquids A and B are 100 and 150 torr respectively. The vapour pressure of solution obtained by mixing 3 moles of A and 2 moles of B will be

Answer 1

Given,

Pa°=100

Pb°=150

Mole fractions of A and B respectively:

Xa=3/5

Xb=2/5

So the pressure of solution is

=Pa°Xa+Pb°Xb

=(100*3+150*2)/5=600/5=120...answer

Answer 2

Hpoe you got your answer thankuuuu
