How much Cu 60 half life 24 min would remain from a 4 mg sample after 48 min?
1mg. If the half life is 24 minutes then in 48 minutes the sample would decay twice. After one half life the mass would halve (to 2mg) and after the second it would have again (to 1mg).
How much Cu-64 would remain from a 2 mg sample after 12 hours?
1mg
If you had a 100 gram sample of plutonium how much would remain in 43 years?
Plutonium-239 has a half-life of about 24,100 years, meaning it takes that long for half of a sample to decay. In 43 years, which is much shorter than the half-life, only a tiny fraction of the plutonium would decay. Therefore, after 43 years, approximately 99.83 grams of the original 100-gram sample would remain.
How much cu half life about 12 hours would remain from a 2 mg sample after 12 hours?
1 mg
How much Cu-61 half-life about 3 hours would remain from a 2 mg sample after 9 hours?
0.25
How much would still remain in 30 minutes if you had a 5 - grm sample of lawrencium?
Lawrencium has a half-life of about 215 minutes. After 30 minutes, about 85% of the original sample would remain. Therefore, approximately 4.25 grams of lawrencium would still be present in a 5-gram sample after 30 minutes.
How much Cu-60 (half-life 24 min) would remain from a 4 mg sample after 48 min?
1mg. If the half life is 24 minutes then in 48 minutes the sample would decay twice. After one half life the mass would halve (to 2mg) and after the second it would have again (to 1mg).
How much Cu 60 half life 24 min would remain from a 4 mg sample after 48 min?
1mg. If the half life is 24 minutes then in 48 minutes the sample would decay twice. After one half life the mass would halve (to 2mg) and after the second it would have again (to 1mg).
How much would lawrencium cost?
Lawrencium is not a commercial product.
How much Cu-60 half-life 24 min would remain from a 4 mg sample after 48 min?
After 48 minutes, two half-lives have passed for Cu-60 (24 min * 2 = 48 min). Each half-life reduces the amount of Cu-60 by half, so after 48 minutes, only 1/4 of the original 4 mg sample would remain, which is 1 mg.
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 cesium would remain from a 10 g sample after 2 years?
5g would remain
How much Cu-64 would remain from a 2 mg sample after 12 hours?
1mg
Will lawrencium combine with other elements?
We would expect Lawrencium to react with other elements similar to the way scandium or yttrium do, these being in the same column of the periodic table. However, lawrencium is highly radioactive, and most of the isotopes have half-lives in the seconds; the longest lived isotope has a half-life of 40 minutes, so that doesn't give chemists much time to work with it.
How much of a 100 gram sample would remain unchanged after 2 hours?
To determine how much of a 100 gram sample would remain unchanged after 2 hours, it is necessary to know the specific decay rate or change process of the sample. For example, if the sample undergoes a decay process with a known half-life, you can calculate the remaining amount using the formula for exponential decay. Without this information, it's impossible to provide an exact answer. In general, if no decay occurs, the entire 100 grams would remain unchanged.
How much Cu-61 would remain from a 2 mg sample after 9 hrs?
.25 mg
How much of a g sample of barium-131 would remain after 36 days?
The mass is 1,075 g.
