Suppose that you take 200 mg of an antibiotic every 8 hr. The​ half-life of the drug is 8 hr​ (the time it takes for half of the
DochEvi [55]

Answer:

600 mg

Explanation:

The initial amount of the drug = 200 mg

The half-life of the drug = 8 hrs

It means that:-

After 6 hours, the concentration becomes :- \frac{200}{2} mg

After 12 hours, the concentration becomes :- \frac{200}{4} mg

After 18 hours, the concentration becomes :- \frac{200}{8} mg

And so on...

Thus,

After infinite time = 200+\frac{200}{2}+\frac{200}{4}+\frac{200}{8}+..

Thus,

After infinite time = 200\times (1+\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+..)

The sum of the infinite series is:- 1+\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+.. = \frac{1}{1+\frac{1}{2}}=2

So,

<u>After infinite time = 200\times 2 mg = 600 mg</u>
