The thorium radioactive decay series produced one atom of `""^(208)Pb` as the final disintegration product of an atom of `""^(232)Th`. `t_((1)/(2))` of `""^(232)Th` is `1.39 xx 10^(10)` years. A certain rock is found to have a mass ratio of `""^(208)Pb and ""^(232)Th` as `14:1`. Determine the age of the rock.
