What is a measure of the amount of a material that will dissolve in another material?
Solubility is the measure of how much of a substance (the solute) can dissolve in another material (the solvent)
If a sample that originally contain 10 grams of C14 has gone through two half-lives of Decay how much C14 will be left?
2.5
How many molecules in aluminum phosphate?
It depends on how much you have of the material.
How much does francium cost for 1 gram?
Francium is not a commercial material.
Why nylon is the best material for a bath towel?
Nylon is not the best material for a bath towel. I believe cotton bath towels are much better.
A particular element has a half-life of 27 days After 54 days have elapsed how much of the radioactive material is left?
1/4. After 27 days, half of the material will have decayed. After another 27 days half of the remaining material will have decayed. Half of half is 1/4.
How much of a radioactive substance remains after 10 hours if its half life is 5 hours?
Since half of the atoms of the original substance will have decayed after 5 hours, half of what is left will have decayed after the next five hours. The answer is 0.25 or one fourth of the original atoms will remain.
How much of the original material is left after 4 billion years?
P222O222R333N33
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.
How much of a 3.0cm material is needed to reduce beam of radiation to 25 percent of its original intensity?
The answer depends on the transmissivity of the material.
How much humus in Calcareous soil?
Anywhere from "none" to "lots and lots". Calcareous soil is soil high in calcium (lime) content. it has nothing to do with the percentage of humus, which is decayed organic material.
How much parent material will be left after five half-lives?
Only 1/32 of the original radioactive material will remain. (½)5 = 1/32
A particular element has a half life of 27 days after 54 days have elapsed how much of the radioactive material is left?
In one cycle, the material would be reduced to one half of the original, leaving one half of the material. In the second cycle (54/27 = 2), there would be 1/2 of that half, leaving 1/4 of the original material.
How much genetic material is found in a cloned cell as compared to the original cell?
nucleus
How much of radioactive substance remains after 15 hours if it's half life is 5 hours?
The half-life of a radioactive substance is the time that it takes for half of the atoms to decay. With a half-life of 10 days, half has decayed in this time. After 20 days, a further 10 days/another half life, a further half of the remainder has decayed, so 1/4 of the original material remains, 1/4 of 15g is 3.75 grams. This is the amount of original radioactive substance remaining, but it’s daughter isotope ( what the decay has produced ) is also present, so the original sample mass is effectively constant, especially in a sealed container. Even in an unsealed container, and assuming alpha ( helium nucleii) emission, a drop in mass per radioactive atom of 4 Atomic Mass units, compared with the original atom of, say 200 amu is only 2% mass decrease, less for heavier decaying nucleii.
Is it true Elastic deformation occurs when a material deforms as stress is applied?
Up to a point, it is possible to elastically deform any material. If the force is released, the material relaxes back to its original shape. If a material is deformed too much, the deformation becomes permanent (plastic deformation) or fracture will occur in a non-ductile material such as glass.
How much time will elapse before only one - fourth of the decayed uranium 237 sample is left?
3,375 days
