Experimental densities, were experimentally determined at 298.15 K for the following mixtures: (i) Binary mixtures: Cyclohexane + n-hexane, cyclohexane + n-octane, cyclohexane + n-decane, cyclohexane + n-dodecane, cyclohexane + n- hexadecane, n-hexane + n-octane, n-hexane + n- octane, n-hexane + n-decane, n-hexane + n-dodecane, and n-Hexane + n-hexadecane. (ii) Ternary mixtures: n-hexane + n-octane + cyclohexane, n- hexane + n-decane + cyclohexane, n-hexane + n- dodecane + cyclohexane, n-hexane + n-hexadecane + cyclohexane. (iii) Quaternary mixtures: n-hexane + n-octane + n-dodecane +...
