A radoactive sample of ^(238)U decay to pb through a process for which the half is 4.5 xx 10^(9) year Find the rate of number of nuclei of pb to ^(238)U after a time of 1.5 xx 10^(9) year Given (2)^(19)= 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) .
