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.

Analysis: Now that you have made your calibration curve, you can
use it to find the concentrations of unknown samples. Look at the
absorbance data for samples taken where the water flows into the
reservoir (inflow) and where the water flows out of the reservoir
(outflow). Compare these values to your graph and estimate the
concentration of each.
