4. A sample of unknown concentration is the same identity as that used to prepare the
calibration graph shown below. The sample of unknown concentration has been diluted by
placing 3.00mL in a 10.00mL volumetric flask and adding water to the calibration line of
the flask. The absorbance of the diluted solution is 0.65 at the wavelength that was used for
the calibration graph (below).
