Solution-Calculate the concentration of pcp in the sample
5.00-mL solution aliquots contain PCP were carefully measured into five separate 50.00-mL volumetric flasks and made basic with KOH. The following volumes of a standard solution of PCP (2.000 µg/mL) were added into each flask: 0.000, 0.500, 1.00, 1.50 and 2.00-mL The fluorimeter readings from each solution are listed below. Calculate the concentration of PCP in the sample.
