Best ResponseYou've already chosen the best response.0Iron59 has a halflife of 45.1 days. How old is an iron nail if the Fe59 content is 25% that of a new sample of iron? Show all calculations leading to a solution. 25=100 e^(.693 t/45.1) Ln(25)=ln(100) .693 t/45.1 ln(25)ln(100)=.693 t/45.1 ln(25/100)=.693t/45.1 t=  45.1/.693 ( ln .25) t=90.2 days.
