Sarah takes 550 mg of an antibiotic. Every hour, her body breaks down 25% of the remaining drug. How much will be left after 12 hours?.

Answers

Answer 1

From the calculations and the information taht we can glean from the question, the mass of the antibiotic left after 12 hours is 8.59 mg.

What is decay?

The term decay has to do with the breakdown of a chemical substance. Since the decay depends only on the initial amount of the drug the process folows the first order kinetics.

Hence;

N = amount left at time t

No= amount initual present

t = time taken

t1/2 = half life of the drug

N/No = (1/2)^t/t1/2

N/550 = (1/2)^12/2

N = 550[(1/2)^12/2]

N = 8.59 mg
