A sample of a radioactive element has a mass of 80 g. How much daughter materials are in the sample after two half-lives?
1 answer:
Answer:
60g
Step-by-step explanation:
A sample of radioactive element has a mass that weighs 80g
The amount of life spent is two half-lives
This means that after two half lives, the number of daughter materials that would be available in the sample is 60g
Hence 60g of daughter cells would be available after two half lives
