How do you determine half life
WebAug 29, 2024 · How do you find the half-life of a drug example? Half life. The half-life of a drug is is the period of time required for its concentration or amount in the body to be reduced by exactly one-half. Example 2. Drug B has a half-life of 3 hours. 6hr = 2 half − life = 1800 ÷ 2 = 900 / 9hr = 3 half − life = 900 ÷ 2 = 450 /. 40 − 32 = 8ℎ = 480. WebThe half-life is plotted as a red point.
