Question
How many grams of pentane, CH3(CH2)3CH3, must be mixed with 64.18 g of hexane, CH3(CH2)4CH3, at 25.00 °C to produce a solution with a vapor pressure above the solution of 273.5 torr? The vapor pressures of pure pentane and hexane at 25.00 °C are 511.0 torr and 150.0 torr, respectively. These compounds form nearly ideal solutions when mixed together.
Expert Solution
