A particular radioactive isotope has a half-life of 4.50 hours. If you have 26.5 g of the isotope at 10:00 AM, about how much will you have at 7:30PM? Provide the answer in grams.
Homework Answers
Given half life = 
Given time duration t = 10 AM to 7 : 30 PM = 9.5 h
Initial quantity = 
Final quantity:
Hence at 7 : 30 PM there will be 3.2 g of the radioactive isotope left.
