Answer» <P> SOLUTION :VAPOUR pressure of chloroform `p_(1)^(0)=200` mm HgVapour pressure of dichloroethane `p_(2)^(0)=415` mm Hg Mole FRACTION of chloroform `n_(1)=0.312` Mole fraction of dichloroethane `=n_(2)=1-0.312=0.6878` `p_(T)=p_(1)^(@)x_(1)+p_(2)^(0)x_(2)` `P_(T)=200xx0.312+415xx0.688` `62.4+285.52=347.9` mm Hg. |
