Every radioactive isotope decays at a certain rate. It is never known when a given nucleus will decay, but if many nuclei are gathered together, as a group they will decay at a measurable and consistent rate. A radioactive half-life is the time it will take for half of the nuclei to decay. Part A Phosphorus-32 has a half-life of 14.0 days. Starting with 8.00 g of 32P, how many grams will remain after 98.0 days ? Express your answer numerically in grams. ► View Available Hint(s) 15| ΑΣΦ ? g Part B Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the ¹4C has decayed to 1/16.0 of the original amount. How long ago was this plant alive? Express your answer numerically in years. ► View Available Hint(s) [-] ΑΣΦ ?
