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
