Question 63616: This is a carbon decay question that I haven't encounted yet. Can anyone give me a hand here? Thanks! According to the text, the half life in carbon-14 dating is 5700 years
Question:
Only 25% of the carbon-14 in a wooden bowl remains. How old is the bowl?
Any help would be appreciated. Thanks!

The idea of half life is that after that time period only half of the original material remains. If you have 25% of the original material then that is half of one half of the original material or two half lives. With a half life of 5700 years for Carbon 14 then the bowl must be 2 x 5700 years old or 11400 years old.
