Find the percent of the drug is still in the patient`s system after 24 hours.
Answer to Problem 9CYU
12.5 %
Explanation of Solution
Given:
A certain drug has a half − life of 8 hours after it is administered to a patient. What percent of the drug is still in the patient`s system after 24 hours?
Concept Used:
If the half life is 8 hours, it means by 8 hours half of the drug is gone.
Calculation:
If the half life is 8 hours, it means by 8 hours half of the drug is gone.
Therefore, by 16 hours, another half will be gone, so
By 24 hours there will another half gone, leaving us with
Thus, 12.5 % of the drug is still in the patient`s system after 24 hours.
