Post by: cliff313342 on Mar 21, 2021 An archaeological sample contains 0.743 g of lead-206 and 2.145 g of uranium-238. Assume that all the lead now present in the rock came from the radioactive decay of the uranium and that no appreciable amounts of other radioactive nuclides are present in the sample. The decay rate constant for the uranium is 1.540 × 10–10/ year. Determine the half-life of the uranium. ▸ 4.500 × 109 years ▸ 1.067 × 10–10 years ▸ depends on the age of the sample ▸ depends on the organic content of the sample ▸ Two of these are correct.
