WebDec 30, 2024 · The half-life of carbon-14 is 5730 years. Therefore, after 1 half-life there is 50% = 1 2 of the original amount left. 2 half-lives there is 25% = 1 4 of the original amount left. 3 half-lives there is 12.5% = 1 8 of the original amount left. 1 − 7 8 = 1 8 So, your answer would be the time it takes for carbon-14 to elapse 3 half-lives. WebSo, we conclude that 0.518 half-lives have passed since the formation of this mineral sample. To determine the absolute age of this mineral sample, we simply multiply y (= 0.518) times the half life of the parent atom (=2.7 million years). Thus, the absolute age of sample = y * half-life = 0.518 * 2.7 million years = 1.40 million years. how can i increase my insurance sales
