For a drug to be effective in treating an illoess, its levels in the bloodstream must be maintainod for a period of time. One way to meanure the level of a drug in the body is te measure ts rate of appearance in the urine. The rate of excretion of penicillin is first erder, with a half-life of about 30. min. If a person receives an injection of 21 mg of penicillin at t-0, bow much penicillin remains in the body after 3.0 hours? mg
