does anyone know how to do this problem?(adsbygoogle = window.adsbygoogle || []).push({});

The total vapor pressure above a solution of [tex]C_6H_6(l)[/tex] and [tex]C_7H_8(l)[/tex] is 0.485 atm. What is the mole fraction of [tex]C_6H_6(l)[/tex] in the liquid solution?

[tex]P^o C6H6(l) = 0.526 atm[/tex]

[tex]P^o C7H8(l) = 0.188 atm[/tex]

the answer is 0.879 but i'm not sure how to get that using the formula [tex]P_A = (X_A)(P^o _A)[/tex]
