10 g of a mixture of A and B is placed in an initially evacuated chamber. The chamber is sealed and maintained at a temperature of 330 K. Using your knowledge of Antoine's equation, you have estimate that the vapor pressures of pure A and B at 330 K are 2.72 and 1.26. When a small bleeder valve is opened at the top of the chamber, a small hiss is heard, indicating the presence of a vapor phase, while a similar valve at the bottom, when opened, releases a small liquid droplet, indicating the presence of liquid in the chamber. You allow the droplet to fall onto a glass slide from which you draw a 0.05 mL sample in a syringe and inject into a gas chromatograph, from which you learn the droplet had 19.29-mol% A. If you assume A and B form ideal liquid mixtures, as well as ideal vapor mixtures, at least at this temperature, then what would you expect to be the equilibrium pressure in the chamber?
