2 liquids a and b have vapour pressure of 500 mm hg and 200 mm hg .calculate mole fraction of a at which 2 liquids have equal partial pressure

    I'm not sure I understand the problem. I interpret this problem as unmixed. If that is true, then you want
    Pa = Xa*Poa = Xa*500
    Pb = Xb*Pob = Xb*200 and since Pa = Pb, then
    Xa*500 = Xb*200
    Xa + Xb = 1 and solve for Xa and Xb. I get something like 143 mm Hg but that is approximate. Let me know if this is not the correct interpretation.
