to prepare a 13.9 kg dog (assume volume of 13.9 L) for surgery, 0.0343 moles of an anesthetic was administered intravenously. The reaction in which the anesthetic is metabolized displayed a first half life of 132.5 minutes and a second half life of 66.26 minutes. After 38.43 minutes of surgery the drug began to lose its effect, but more surgery was required. How many moles of the anesthetic must be re-administered to restore the original level of the anesthetic?
