At 20" vapor pressure of benzene (CsH6) is 75 tort, and that of toluene is (C-Hs) is 22 torr, Both are volatile solvents. Assuming they form an ideal solution, what is the mole fraction for each component when a mixture of the two solvents has a vapor pressure of 35 torr at 20°C. (Hint: look at page 544 in your text.)
