Reference no: EM131057077

An archaeological sample contains 1.373 g of lead-206 and 3.567 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 half-life of 238- uranium is 4.51 x 10^9years. What is the age of the sample?
