Enrofloxacin is a drug used for dogs and cats to combat bacterial infections.A dog was given an intramuscular injection of enrofloxacin, and just after the injection, the initial concentration of the drug in the dog’s blood was 5.8Í10–6 M. If the enrofloxacin disappears in a first-order process with a half-life of 4.6 hours, how many hours will it take for the enrofloxacin concentration of drop to one-eighth (1/8th) of the initial concentration (i.e., 0.125[A]0)?

Question

  1. Enrofloxacin is a drug used for dogs and cats to combat bacterial infections.
    A dog was given an intramuscular injection of enrofloxacin, and just after the injection, the initial

    concentration of the drug in the dog’s blood was 5.8Í10–6 M.

    If the enrofloxacin disappears in a first-order process with a half-life of 4.6 hours, how many hours will it take for the enrofloxacin concentration of drop to one-eighth (1/8th) of the initial concentration (i.e., 0.125[A]0)?
