Answer: A sample f thorium-234 has a half life of 24.1 days. Will all the thorium undergo radioactive decay in 48.2 days? No, ¼ of the original mass will remain.
Explanation:
:}
Answer:
No, it will still have 58.8 g of mass
Explanation:
If the half-life of Thorium 234 is24.1 days, then 24.1 days have passed, Thorium will lose half its mass. Its initial mass is 234, so after 24.1 days it will be halved: 117
If pass more 24.1 days, it willlost the half of its mass again, so the half of 117: 58.5.
If you add the days, 24.1 + 24.1, it will give 48.2. So the sample will still have 58.5 of mass before 48.2 days.
