A standard addition procedure is used for analysis of O2 in a fluid via a coulometric method in which the measured current corresponds linearly with concentration. A patient's fluid (1.00 mL) is measured directly with current 69.7 μamps , and then spiked with 100 microliters of a 0.500 ppm solution of O2 . The spiked sample had current 76.2 μamps. Determine the concentration of O2 in the patient's fluid. Data: Reagent blank is 35 μamp, patient’s fluid is 69.7 μamps, spiked sample is 76.2 μamps. make sure to correct for the blank
