Just over 6 half lives.
If ' L ' is the number of days in one half-life, then the number of half-lives in 32 days is (32 / L) .
Depends on the drug's half-life
After 8.1 days, three half-lives have passed for Au-198 (2.7 days/half-life * 3 half-lives = 8.1 days). Each half-life reduces the number of atoms by half, so remaining atoms = 800 atoms * (1/2)^3 = 100 atoms.
It is 10 days. I have live in New York for about half my life.
1250 on day six
no days just half an hour
The answer is 2. If after one half-life only half of the element remains, then after another half-life half of what was there only remains. So a half of a half is a quarter (or a fourth). So that's 2 half-lives.
A half-life is simply the amount of time it takes for a substance to reduce itself by half. In this case, every 14.2 days half of plutonium-32 is converted into something else. All you have to do is divide 99.4 by 14.2, which is exactly 7. About 0.78% of the plutonium will be remaining at this time.
9 and a half days = 9 and a half days , 228 hours, 13680 minutes, 820800 seconds.
After 8.1 days, three half-lives have passed (8.1 days / 2.7 days = 3). With each half-life, the number of atoms is halved. Therefore, starting with 800 atoms, after three half-lives there would be 800 / 2 / 2 / 2 = 100 atoms remaining.
Two and a half days is 60 hours.
In 3 days there are 144 half hours.
