Carbon 14 has a half-life of 5700 year, scientist use this fact to determine the age of things made of organic material. Suppose the average page of a book containing aprox. 0.5mg of Carbon 14 is put into a time capsule how much carbon 14 will each page contain after each of the following number of years. A. 5,700 B. 11,400 C. 22,800 D. 34,200

How do I go about this?

**Rhonda**, Sunday, December 9, 2007 at 4:46pmWell, we know that half of it will change into another form in 5700 years, so if you start with .5 mg than in 5,700 years you would have half or .25 mg. 11,400 is another half life so half of .25 = .125 mg. 22,800 is two more half lives so half .125 twice.
