If you were to take 200 milligrams of Advil how many milligrams will remain in the
body 10 hours later? Answer to two decimal places. Show your workings in
detail using the equation.
To determine the amount of Advil remaining in the body after 10 hours, we can use the concept of half-life. The half-life of ibuprofen (the active ingredient in Advil) is approximately 2 hours.
The amount of Advil remaining in the body after a certain amount of time can be calculated using the formula:
Amount remaining = Initial amount x (1/2)^(time elapsed/half-life)
In this case, the initial amount is 200 mg, the time elapsed is 10 hours, and the half-life is 2 hours.
Amount remaining = 200 mg x (1/2)^(10/2)
Amount remaining = 200 mg x (1/2)^5
Amount remaining = 200 mg x 1/32
Amount remaining = 200/32
Amount remaining = 6.25 mg
Therefore, after 10 hours, approximately 6.25 mg of Advil will remain in the body.
