reservoir (inflow) and where the water flo (outflow). Compare these values to your graph and estimate the concentration of each. ESTIMATED Concentration (M) Absorbance Inflow: 0.17 Outflow: 0.85 Now, on your graph, select the "Use Equation" option to "Label" your trendline. Write the equation you get below (in y=mx+b form) y = - X + Recall that Absorbance is your y-axis and Concentration is your x-axis. Plug each Absorbance value into your equation for "y" and solve for "x", the Concentration. Show calculations and record.
