Best ResponseYou've already chosen the best response.1One half life is the time that takes to decrease the amount of the nucleoide in half of the original amount. That means that in 45.1 days (one half life) you will have 50% of the original amount of Fe59 compared with the new sample of iron In two half life (45.1 days x 2) you will have 50% of the 50%, that means 25% of the new sample contents. What do you think is the answer?

Best ResponseYou've already chosen the best response.025%=25/100 =1/4. (1/2)n=1/4.so, n=2 half lives. 45.1 days x 2 half lives=90.2 days . Right?
