The title diidnt catch my attention, but yet i clicked just to post this..
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?
answers plawks?
already looked in my bio book and i couldnt find it...

6.25 Grams of parent material left.
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?
