WebTo find the half-life of the element, we need to determine the time it takes for the amount of the element to be reduced to half of its initial value. We can set A(t) = 0.5A(0), where A(0) is the initial amount of the element, and solve for t to find the time it takes for the amount to decay to half. 0.5A(0) = A(0) e^(-kt) 0.5 = e^(-kt) WebProblem #3: Os-182 has a half-life of 21.5 hours.

WebStep-by-step explanation. The radioactive element C-14 has a half life of 5750 years. We can write in terms of equation. Let n is the number of half lives elapsed; fraction remaining as F o. F o = 0.5 n. The fraction of C-14 left in the mastodon; F o = 1 - 0.737 = 0.263. 0.263 = 0.5 n. Taking logarithm on both sides. WebCalculating Half-Life in Chemistry 1.
