A 200-mg dose of a drug is injected intravenously into a human subject. The drug rapidly distributes into an apparently homogeneous fluid volume. Ten hours after injection, the plasma concentration of drug is 3.28 mg/mL. At 16.92 hours after injection, the plasma concentration of drug is 1.64 mg/mL. Calculate: (i) the biological half-life, (ii) elimination rate constant, (iii) volume of distribution, and (iv) plasma clearance.
