Benzene (C_(6)H_(6)) and toluene (C_(7)H_(8)) from a nearly ideal solution at 313 K. The vapour pressure of pure benzene and toluene are 160 mm of Hg and 60 mm of Hg respectively. Calculate the partial pressure of benzene and toluene and the total pressure over the following solutions : (iii) containing equal molecules of benznen and toluene.

Answer»


SOLUTION :(III) `n_(B)=N//T_(0), n_(T)=N//N_(0)." Hence, "n_(B)=n_(T)=0.5.""("N = No. of molecules, "N_(0)=" AVOGADRO's No.")`
