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.
<h3>What is decay?</h3>
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
