Abstract: The molar volumes were determined for the binary mixtures such as benzene-cy-clohexane and benzene-n-hexane at 288.15, 293.15, 298.15, 303.15 and 308.15 K and 250 kPa. For these binary systems, their pressure coefficients have been calcu-lated. The isothermal compressibility of pure liquid coincided well with those from previous measurements.

Key words: Benzene, n-Hexane, Cyclohexane, Isothermal compressibility, Pressure coefficient
