A patient received 250mg of a drug at noon, 6 pm, and midnight. The half-life of the drug is 6 hours. Fill in the table below to
n200080 [17]

Based on the half-life of the drug, the amount remaining at 6 am is 218.75 mg.

<h3>What is half-life of a substance?</h3>

The half-life of a substance is the the time taken for half the initial amount of that substance to decompose or decay.

The half-life of a substance follows a decay constant.

Considering the given drug:

The half-life of the drug is 6 hours meaning that after every 6 hours, half the initial amount will remain.

The patient received 250mg of a drug at noon, 6 pm, and midnight.

Amount remaining at 6 am the next day is determined as follows:

Initial amount at Noon = 250 mg

Amount at 6 pm = 250/2 + 250 = 375 mg

Amount remaining at 12 am = 375/2 + 250 = 437.5 mg

Amount remaining at 6 am = 437.5/2

Amount remaining at 6 am = 218.75 mg

In conclusion, the half-life tells how long the drug will remain in the body of the patient.
