The concentration of chloride in seawater can be determined by a flow injection analysis. The analysis of a set of calibration standards gives the following results. [Cr] (ppm) absorbance 5.00 0.07125 10.00 0.12375 20.00 0.2875 30.00 0.4425 40.00 0.5975 50.00 0.7425 75.00 1.0500 A 1.00-ml sample of seawater is placed in a 500 mL volumetric flask and diluted to volume with distilled water. When injected into the flow injection analyzer an absorbance of 0.443 is measured. What is the concentration of CI in the sample? O a. 12980 ppm Ob. 30.78 ppm O. 15400 ppm O d. 51.76 ppm Oe. 16330 ppm
