Practice question
Question
A solution of two volatile liquids has vapor pressures of 250 mm Hg and 350 mm Hg for pure components. If the mole fraction of the first is 0.6, what is the total vapor pressure?
Explanation
Mole fraction of second = 1 - 0.6 = 0.4 . Total vapor pressure = 250 × 0.6 + 350 × 0.4 = 150 + 140 = 290 mm Hg .
