A radioactive sample of ^(238)U decay to Pb through a process for which the half is 4.5 xx 10^(9) year. Find the ratio of number of nuclei of Pb to ^(238)U after a time of 1.5 xx 10^(9) year Given (2)^(1//3)= 1.26

U^238 decays to (Pb)^206 with a half-life of 4.47xx10^9 y.The ratio of number of nuclei of pb to u 238 after a time of 1.5 .10 power 9 years given 21/3=1.26

A rock is 1.5 xx 10^(9) years old. The rock contains .^(238)U which disintegretes to form .^(236)U . Assume that there was no .^(206)Pb in the rock initially and it is the only stable product fromed by the decay. Calculate the ratio of number of nuclei of .^(238)U to that of .^(206)Pb in the rock. Half-life of .^(238)U is 4.5 xx 10^(9). years. (2^(1/3) = 1.259) .
