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.
What total mass of a 16 gram sample of 60co will remain unchanged after 15.8 years?
The half-life of 27Co60 is about 5.27 years. 15.8 years is 3 half-lives, so 0.53 or 0.125 of the original sample of 16 g will remain, that being 2 g.
How much of a 100 gram sample of isotope remain unchanged after two hours?
To determine how much of a 100-gram sample of an isotope remains unchanged after two hours, we need to know its half-life. For example, if the half-life is one hour, after two hours, two half-lives would have passed, resulting in 25 grams remaining (100g → 50g after one hour, then 50g → 25g after another hour). If the half-life is different, the remaining amount would be calculated accordingly. Please specify the half-life for a precise answer.
What would cause allele frequencies to remain unchanged?
Only one thing: extinction.

How many unchanges atoms would remain after 3 half lives if the initial sample had 600 unchanged atoms?
After 3 half-lives, half of the original sample would remain unchanged. After the 1st half-life: 300 unchanged atoms. After the 2nd half-life: 150 unchanged atoms. After the 3rd half-life: 75 unchanged atoms would remain.
What total mass of a 16 gram sample of 60co will remain unchanged after 15.8 years?
The half-life of 27Co60 is about 5.27 years. 15.8 years is 3 half-lives, so 0.53 or 0.125 of the original sample of 16 g will remain, that being 2 g.
Molybdenum-99 has half a half-life of 66 hours. after 132 hours how much of an initial sample of 10 ci of mo-99 would remain?
After 132 hours, 1/4 of the initial sample of 10 Ci of Mo-99 would remain. Since the half-life is 66 hours, after 66 hours half of the sample would remain (5 Ci), and after another 66 hours (totaling 132 hours), half of that remaining amount would be left.
How much Cu -64 would remain from 2mg sample after 12 hours?
Copper-64 (Cu-64) has a half-life of approximately 12.7 hours. After one half-life (12.7 hours), half of the original sample would remain. Therefore, from a 2 mg sample, after 12 hours, approximately 1 mg of Cu-64 would remain, as it has not yet fully completed one full half-life.
How much Cu-64 half-life about 12 hours would remain from a 2 mg sample after 12 hours?
1 mg
How much Cu-64 would remain from a 2 mg sample after 12 hours?
