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>

Hydrogen Peroxide slowly decomposing into water and oxygen increases the entropy of the universe. Any reaction of a system always increases the degree of the orderliness of the universe. Decomposition is one of the best examples of increasing the entropy. This is when substance is broken down further to elements or other compounds.
