SOLUTION: The half-�life of a radioactive substance is the time it takes for half of the atoms of the substance to disintegrate. All life on Earth contains Carbon�14, which decays continuous

Question 1072846: The half-�life of a radioactive substance is the time it takes for half of the atoms of the substance to disintegrate. All life on Earth contains Carbon�14, which decays continuously at a fixed rate. The half-�life of Carbon-14 is 5760 years. That is, every 5760 years half of a mass of Carbon-14 decays away. If a specimen that originally contained 150 milligrams of Carbon�14 now contains 130 milligrams, how old is the fossil?
