A sample of hydrogen chloride gas, HCl, is being collected by bubbling it through liquid benzene. Assume that the molecules pictured as spheres show a representative sample of the mixture of HCl and benzene vapor (⚫represents an HCl molecule and ⚪ a benzene molecule).

(a) Use the figure to determine the mole fractions of HCl and benzene vapor in the gas inside the container.

(b) What are the partial pressures of HCl and benzene in the container when the total pressure inside the container is 0.80 atm?
