Extracted text: 13-2. The following data were obtained for a series of binary mixtures of benzene, and cyclohexane at 20°C. Wt % Benzene 10.86 1.38490 1.41071 36.48 55.98 70.41 82.83 1.43396 1.45334 1.47115 (a) Plot the data. (b) Derive an equation for the line assuming a linear relationship. (c) Calculate the standard deviation for the slope and about re- gression. d) Calculate the weight percent benzene in a mixture that had a refractive index of 1.43216. (e) Calculate the standard deviation of the result found in part (d). (f) The mean of 3 refractive index measurements of a benzene/ cyclohexane mixture was 1.46437. Calculate the weight per- cent benzene. (g) Calculate the standard deviation of the result found in part (f).
