How many half-lives have passed after 32 days?
If ' L ' is the number of days in one half-life, then the number of half-lives in 32 days is (32 / L) .
How many days does pills stay in your system?
Depends on the drug's half-life
How many days is one half- life?
One half-life is the time required for half of a substance to decay or transform into another substance. The specific duration of a half-life varies depending on the material or isotope in question; for example, the half-life of carbon-14 is about 5,730 years, while that of iodine-131 is approximately 8 days. Therefore, without specifying a particular isotope, one cannot determine a standard duration for a half-life in days.
How many atoms would remain of Au-198 that has 800 atoms after 8.1 days if its half-life is 2.7 days?
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.
How many absent days are allowed in elementary school in new york?
It is 10 days. I have live in New York for about half my life.
You start out with 10000 radioactive atoms Their half life is 2 days How many will remain in 6 days?
1250 on day six
Half an hour is how many days?
no days just half an hour
If the half life of an element is 5 days and 100 milligrams of the element is initially available how many milligrams (mg) of the element is available after 20 days?
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.
Plutonium-32 has a half-life of 14.2 days How many half-lives have passed in 99.4 days?
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.
How many days in 9 and a half days?
9 and a half days = 9 and a half days , 228 hours, 13680 minutes, 820800 seconds.
The half-life of Au-198 is 2.7 days When there are 800 atoms of Au-198 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 8.1 days how many atoms of Au-198 remaining?
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.
How many hours are there in 2 and a half days?
Two and a half days is 60 hours.
