A solution is made by mixing 52.1 g of propyl chloride, C3H7Cl, and 38.4 g of propyl bromide, C3H7Br. What is the lowering of the vapor pressure of propyl chloride at 25°C in this solution? The vapor pressure of pure propyl chloride is 347 torr at 25°C and that of pure propyl bromide is 133 torr at 25°C. Assume that the solution is an ideal solution.
