89. The differential pulse polarogram of 3.00 mL of solution containing the antibiotic tetracycline in 0.1 Macetate, pH 4, gives a maximum current of 152 nA at half-wave potential of -1.05 V. (vs S.C.E). When 0.500 mL containing 2.65.ppm of tetracycline was added, the current increased to 206 nA. How much tetracycline, in ppm, is in the original solution?
