Question
Calculate the fraction of an iv dose remaining in the body at 12 hrswhen the half life is 6hrs
Solution
Sure, here's how you can calculate the fraction of an IV dose remaining in the body at 12 hours when the half-life is 6 hours.
-
First, understand that the half-life is the time it takes for the quantity of the substance (in this case, the IV dose) to reduce to half its initial amount.
-
Given that the half-life is 6 hours, this means that after 6 hours, half of the initial dose will remain in the body.
-
After another 6 hours (i.e., at 12 hours), half of the remaining dose will again be eliminated. This means that at 12 hours, 1/2 * 1/2 = 1/4 of the initial dose will remain in the body.
So, the fraction of the IV dose remaining in the body at 12 hours is 1/4 or 0.25.
