1.	At `40^(@)C` the vapour pressure of pure liquids, benzene and toluene, are `160 mm Hg` and `60 mm Hg` respectively. At the same temperature, the vapour pressure of an equimolar solution of the liquids, assuming the ideal solution will be:A. 140mm HgB. 110mm HgC. 220mm HgD. 100mm Hg
Answer» Correct Answer - B `p_("total")=p_(1)^(@)x_(1)+p_(2)^(@)x_(2)` `160xx(1)/(2)+60xx(1)/(2)=110mm" Hg"`
