A sample of radioactive isotope has a halflife of 1 day how much of the original sample will be left at the end of the fourth day?
If a sample of radioactive material has a half-life of one week the original sample will have 50 percent of the original left at the end of the second week. The third week would be 25 percent of the sample. The fourth week would be 12.5 percent of the original sample.
How much of the original sample will be left at the end of the second day if a sample of radioactive isotope has a half life of 1 day?
Hi, Each half-life means the mass of the sample has decreased by 1/2 its mass. Thus; After 1 half-life, 1/2 the sample has decayed. After 2 half-lives 3/4 of the sample has decayed. Hope this helps.
Does uranium 238 have the shortest half life?
No, uranium-238 has a long half-life of about 4.5 billion years. It is a naturally occurring isotope that is commonly found in nature. Shorter-lived isotopes, such as radon-222 or polonium-214, have much shorter half-lives.
How much ice water will it take to cool the sample to 20 degrees celsius?
To calculate the amount of ice water needed to cool the sample to 20 degrees Celsius, you would need the initial temperature of the sample, the mass of the sample, and the specific heat capacities of water and ice. With this information, you could use the equation q = m * c * ΔT to determine the quantity of ice water needed to cool the sample.
A measure of amount of matter?
Mass is the amount of matter in a sample of a substance. Mass translates directly to how much matter is in something, in other words, how many atoms are crammed into it.

How much cesium is left after 4 half-lives?
1/16 of the original sample of any unstable element remains after 4 half lives.
What kind of protective equipment is there after a radioisotope is ingested?
None, I am afraid. Once the radioisotope is INSIDE the body, any EXTERNAL protective equipment is useless. The only helpful approach would be aiding the excretion of the radioactive substance, but the possibility of eliminating the radioisotope (through the urine, faeces, breath or sweat) depends very much on the type of isotope and on its chemical form-
What property depends on the amount of matter in the sample?
Depends on what the sample is and how much of it you have.
You took percocet on Friday will it show on monday?
depends on how much, but opiates halflife is anywhere from 12 to 72 hours. drink alot of water in the next couple of days and you should be safe
How much time is needed for radioisotope to decay into its stable daughter product?
There is no one answer for an individual atom, but for a given radioisotope we usually quantify the rate of decay via the half-life, i.e. the average time it takes for half of the atoms of an isotope to decay. Realizing that some isotopes will decay to another radioisotope before eventually decaying to a stable product, this can get even more complicated. In mathematical terms the equation for concentration of the radioisotope approaches zero asymptotically. The math says that you will never get zero concentration - but of course atoms are discrete entities so that once the concentration predicted by the math drops below one atom, you have reached zero in the real world.
How much of a 100 gram sample would remain unchanged after two hours?
This would depend on the specific sample and its stability. Without additional information, it is not possible to determine how much of the sample would remain unchanged after two hours.
How much error between sample mean and population mean?
The answer depends on the underlying variance (standard deviation) in the population, the size of the sample and the procedure used to select the sample.
How much money did The Remains of the Day gross worldwide?

How much of Earth's land remains unexplored?
Approximately 80 of Earth's land remains unexplored.
If Uranium has a halflife of 1 day how much is left at the end of the third day?
The half life of uranium is not one day. For an isotope with the half life or one day, after 3 days: the quantity remained is 12,5 %.
