Carbon-14 has a half-life of 5700 yrs. Scientists use this fact to determine the age of things made of organic material. Suppose the average page of a book containing approximately 0.5 mg of carbon-14 is put into a time capsule. How much c-14 will each page contain after 5700 yrs.
.
Since 5700 years is the "half-life" exactly
0.25 mg will remain.
