Web23 nov. 2024 · The half-life of carbon-14 is 5730 years. What is the formula of exponential decay? The formula for exponential decay is, If the half-life is 5730 years, then. ln 0.125=ln e^.00012096809t =.00012096809t ln e =-0.00012096809t. t=17,190 years. t=17,190 years. Therefore, it takes for 7/8 of a sample of carbon-14 to decay is 17190 years. To learn ... WebGiven that the half-life of carbon 14 is 5,730 years. So, t 1 2 = 5730 years. Find the decay constant k by using the formula, k = ln 2 t 1 / 2. k = ln 2 5730 ≈ 0. 000121 Since a bone becomes 70% of its original carbon 14. Therefore, A = 0. 7 A 0. Substitute 0. 7 A 0 for A, 0.000121 for k into the equation A = A 0 e - k t and simplify.
Web6 feb. 2014 · Feb 6, 2014 Carbon-14 has a 5,730 year half-life, meaning that every 5,730 years, about half of an artifact's C-14 will have decayed into the stable (non-radioactive) isotope nitrogen-14. Its presence in organic materials is the basis of radiocarbon dating to date archaeological, geological and hydrogeological samples.
