Suppose you start with 100 grams of the radioactive isotope Carbon-14, which has a half-life of 5,000 years. After 20,000 years, how much parent material will remain and how much daughter material will be produced?
already looked in my bio book and i couldnt find it...

How? Half life of a radioactive material is x. Meaning, every x years the amount of radioactivity will have dropped by 50%. See where this is going? Find the daughter material yourself.
And mega tons = million tons. He is trolling, that would be 10,000,000,000 pounds. (10 billion.) Now how the fuck would that come out out of 100 grams?
Damn my high school freshmen classes are so behind
All I know is radioactive decay
