Problem

β-Pinene (C10H16) and α-terpineol (C10H18O) are used in cosmetics to provide a “fresh pine” scent. At 367 K, the pure substances have vapor pressures of 100.3 torr and 9.8 torr, respectively. What is the composition of the vapor (in terms of mole fractions) above a solution containing equal masses of these compounds at 367 K? (Assume ideal behavior.)
