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 :-
mg
After 12 hours, the concentration becomes :-
mg
After 18 hours, the concentration becomes :-
mg
And so on...
Thus,
After infinite time = 
Thus,
After infinite time = 
The sum of the infinite series is:-
= 
So,
<u>After infinite time =
mg = 600 mg</u>
