92. Solving a chemistry problem

9. For a mixture of benzene and carbon disulfide, the relationship between the composition of the solution and the composition of the vapor is expressed by the equation: (1-y) / y \u003d 3.32 [(1-x) / x] 0.9, where x is the mole fraction of benzene in solution, y is the mole fraction of benzene in vapor. Determine the composition of the vapor in mole fractions that are in equilibrium with a solution containing: a) 90% benzene and b) 10% benzene.
