Slope of the line from Beer's law plot: Use your slope to calculate the molar absorptivity of Red #40 at the analytical wavelength. (Include units) Use the absorbance measured for your unknown to calculate its ORIGINAL concentration. (hint: find diluted molarity first, then calculate concentrated molarity)
