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