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).
