For Part I, generate a graph of height of liquid $($cm$)$ on the x$-$axis vs$.$ optical rotation in degrees on the y$-$axis. You may do this by hand, in excel, or any other graphing program that you are comfortable. Answer the following: a$.$ What is the relationship between sample height and optical rotation $($direct$,$ inverse, exponential etc$)?$ explain your answer b$.$ Find the best$-$fit line $($ie$,$ equation of the line$)$ and calculate the angle of rotation when the sample height is $12\mathrm{.}0$ cm$?$ Show calculations
