SUMMARY
The discussion centers on calculating the slope of a Beer's Law calibration curve using Excel. The user derived the equation y = 228.19x + 0.0369 from their graph of Absorbance versus Concentration. The consensus confirms that the slope of 228.19 is indeed the correct value to use for determining concentrations of other absorbances in subsequent lab work, provided that the axes are correctly assigned.
