Answer :
Final answer:
The correct option is (a) After 170 days: 0.25 kg, After 340 days: 0.0625 kg, based on the calculation of remaining isotope after each half-life of 87 days. In the case of the isotope with a half-life of 87 days, you can calculate the remaining amount of the isotope after certain days using this principle.
Explanation:
The half-life of a particular isotope is the time it takes for half of the isotope to decay. In the case of the isotope with a half-life of 87 days, you can calculate the remaining amount of the isotope after certain days using this principle.
After one half-life (87 days), half of the original 1 kilogram (0.5kg) remains. After two half-lives (170 days), half of the remaining 0.5kg decays, leaving 0.25kg remaining. Finally, after four half-lives (340 days), 0.0625kg of the original isotope remains.The correct option is (a) After 170 days: 0.25 kg, After 340 days: 0.0625 kg, based on the calculation of remaining isotope after each half-life of 87 days
So, the correct option is (a) After 170 days: 0.25 kg, After 340 days: 0.0625 kg.
