Aminabhavi et al. [T. M. Aminabhavi, V. B. Patil, M. I. Aralaguppi, J. D. Ortego and K. C. Hansen, J. Chem. Eng. Data 41, 526 (1996)] examined mixtures of cyclohexane with various long-chain alkanes. Among their data are the following measurements of the density of a mixture of cyclohexane and pentadecane as a function of mole fraction of cyclohexane (xc) at 298.15 K:
xc 0.6965 0.7988 0.9004
½ (g/cm3) 0.7661 0.7674 0.7697
Compute the partial molar volume for each component in a mixture that has a cyclohexane mole fraction of 0:7988.
