Abstract:  The values of total vapour pressure were determined over liquid solutions of known composition of the binary systems n-heptane —toluene and toluene — dimethylformamide at 40°C are presented. By using the coexistence equation the equilibrium composition in vapour phase as well as the activity coefficients of the components in liquid solutions have been calculated.
