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.
WebMar 13, 2014 · You calculate the half-life from the amount of material that disappears in a given time. Half-life (t_½) is the time required for the nuclei to decay to half of the original amount. Radioactive nuclei decay according to the equation: Equation 1: N_t /N_0 = e^(—λt), where N_0 is the initial number of nuclei at time t = 0. N_t is the number of nuclei that … WebJan 30, 2024 · Use Equation 3 to calculate the half-life of the reaction.
