Build a stagger plot (3 individual points, do not connect them) using the midpoint of the standards (benzophenone, vanillin and benzoic acid) melting point ranges where observed melting point is on x axis, and literature melting point on y axis. Obtain the line of best fit from the plot (include y=mx+b equation and R2 value on graph). Make sure to label your graph axis appropriately (include units) and to scale the data appropriately. You can copy and paste the graph directly from excel to paste here: Figure 1: Calibration Curve of Melting Point Apparatus Using Benzophenone, Vanillin and Benzoic acid ?
