Question 9 (3 points) Listen The refractive indices of cyclohexane and toluene are 1.4264 and 1.4967, respectively, at 20 °C. A mixture of these two liquids had a refractive index of 1.4563 at that same temperature. Assuming that the relationship between the refractive index and the concentration is linear, calculate the mol fraction of cyclohexane in the sample. The answer should be in the decimal form 0.###, three sig figs.
